Credits to Mu Sigma for supporting the development of the package.
Note - To enable pipelines involving Spark tasks, the package uses the 'SparkR' package.
The SparkR package needs to be installed to use Spark as an engine within a pipeline. SparkR is distributed natively with Apache Spark and is not distributed on CRAN. The SparkR version needs to directly map to the Spark version (hence the native distribution), and care needs to be taken to ensure that this is configured properly.
To install SparkR from Github, run the following command if you know the Spark version: 'devtools::install_github('apache/spark@v2.x.x', subdir='R/pkg')'.
The other option is to install SparkR by running the following terminal commands if Spark has already been installed: '$ export SPARK_HOME=/path/to/spark/directory && cd $SPARK_HOME/R/lib/SparkR/ && R -e ""devtools::install('.')""'.",2019-01-08,Mu Sigma,,TRUE,,1312,10,1552218953

When combined, it's quite simple to decompose time series, detect anomalies,
and create bands separating the ""normal"" data from the anomalous data at scale (i.e. for multiple time series).
Time series decomposition is used to remove trend and seasonal components via the time_decompose() function
and methods include seasonal decomposition of time series by Loess (""stl"") and
seasonal decomposition by piecewise medians (""twitter""). The anomalize() function implements
two methods for anomaly detection of residuals including using an inner quartile range (""iqr"")
and generalized extreme studentized deviation (""gesd""). These methods are based on
those used in the 'forecast' package and the Twitter 'AnomalyDetection' package.

At some point during the design process, a clinical trial researcher who is designing a basic two-arm Bayesian randomized clinical trial needs to make decisions about power and sample size within the context of hypothesized treatment effects. Through simulation, the simple_sim() function will estimate power and other user specified clinical trial characteristics at user specified sample sizes given user defined scenarios about treatment effect,control group characteristics, and outcome. If the clinical trial researcher has access to historical control data, then the researcher can design a two-arm Bayesian randomized clinical trial that incorporates the historical data. In such a case, the researcher needs to work through the potential consequences of historical and randomized control differences on trial characteristics, in addition to working through issues regarding power in the context of sample size, treatment effect size, and outcome. If a researcher designs a clinical trial that will incorporate historical control data, the researcher needs the randomized controls to be from the same population as the historical controls. What if this is not the case when the designed trial is implemented? During the design phase, the researcher needs to investigate the negative effects of possible historic/randomized control differences on power, type one error, and other trial characteristics. Using this information, the researcher should design the trial to mitigate these negative effects. Through simulation, the historic_sim() function will estimate power and other user specified clinical trial characteristics at user specified sample sizes given user defined scenarios about historical and randomized control differences as well as treatment effects and outcomes. The results from historic_sim() and simple_sim() can be printed with print_table() and graphed with plot_table() methods.

for Data from NMR Spectroscopy on Proteins, Peptides, Nucleic Acids, and other Biomolecules. Currently, 'BMRB' offers an R package
'RBMRB' to fetch data, however, it doesn't easily offer individual data file downloading and storing in a local directory. When using
'RBMRB', the data will stored as an R object, which fundamentally hinders the NMR researches to access the rich information from raw
data, for example, the metadata. Here, 'BMRBr' File Downloader ('BMRBr') offers a more fundamental, low level downloader, which will
download original deposited .str format file. This type of file contains information such as entry title, authors, citation, protein
sequences, and so on.
Many factors affect NMR experiment outputs, such as temperature, resonance sensitivity and etc., approximately 40% of the entries in the 'BMRB' have
chemical shift accuracy problems [1,2] Unfortunately, current reference correction methods are heavily dependent on the availability of
assigned protein chemical shifts or protein structure. This is my current research project is going to solve, which will be included
in the future release of the package. The current version of the package is sufficient and robust enough for downloading individual
'BMRB' data file from the 'BMRB' database <>. The functionalities of this package includes but not limited:
* To simplifies NMR researches by combine data downloading and results analysis together.
* To allows NMR data reaches a broader audience that could utilize more than just chemical shifts but also metadata.
* To offer reference corrected data for entries without assignment or structure information (future release).

checkpoint,"The goal of checkpoint is to solve the problem of package
reproducibility in R. Specifically, checkpoint allows you to install packages

packages required or called by your project and scripts to a local library
exactly as they existed at the specified point in time. Only those packages
are available to your project, thereby avoiding any package updates that came
later and may have altered your results. In this way, anyone using checkpoint's
checkpoint() can ensure the reproducibility of your scripts or projects at any
time. To create the snapshot archives, once a day (at midnight UTC) Microsoft
refreshes the Austria CRAN mirror on the ""Microsoft R Archived Network""

The methods differ from past approaches by accounting for the level of clinical treatment efficacy overall and in biomarker response subgroups, which enables the correlates of risk results to be interpreted in terms of potential correlates of efficacy/protection. The methods also account for inter-individual variability of the observed biomarker response that is not biologically relevant (e.g., due to technical measurement error of the laboratory assay used to measure the biomarker response), which is important because power to detect a specified correlate of risk effect size is heavily affected by the biomarker's measurement error. The methods can be used for a general binary clinical endpoint model with a univariate dichotomous, trichotomous, or continuous biomarker response measured in active treatment recipients at a fixed timepoint after randomization, with either case-cohort Bernoulli sampling or case-control without-replacement sampling of the biomarker (a baseline biomarker is handled as a trivial special case). In a specified two-group trial design, the computeN() function can initially be used for calculating additional requisite design parameters pertaining to the target population of active treatment recipients observed to be at risk at the biomarker sampling timepoint. Subsequently, the power calculation employs an inverse probability weighted logistic regression model fitted by the tps() function in the 'osDesign' package.
