Write a function that reads a directory full of files and reports the number of completely observed cases in each data file. The function should return a data frame where the first column is the name of the file and the second column is the number of complete cases.

complete.R

complete <- function(directory, id = 1:332) {
  ## 'directory' is a character vector of length 1 indicating
  ## the location of the CSV files
  
  ## 'id' is an integer vector indicating the monitor ID numbers
  ## to be used
  
  ## Return a data frame of the form:
  ## id nobs
  ## 1  117
  ## 2  1041
  ## ...
  ## where 'id' is the monitor ID number and 'nobs' is the
  ## number of complete cases
  
  source(file='getmonitor.R')
  output <- data.frame()
  
  for ( i in id) {
    # 
    oneMonitorData <- getmonitor(id=i, directory=directory)
    # print(head(oneMonitorData))
    
    one.nobs <- nrow(oneMonitorData[complete.cases(oneMonitorData),])
    
    id.num <- as.integer(x=i)
    one.row <- c(id.num, one.nobs)
    
    # print(one.row)
    
    output <- rbind(output, one.row)
  }
  # print(one.row)
  # print(as.data.frame(one.row))
  
  colnames(output) <- c('id', 'nobs')
  output
}

It says it cannot find the function getmonitor...Please can you give me the full code and help me with the assignment because I am a noob programmer and just learning how to do it! But have to submit the assignment by tomorrow..please Help!!!

I just wanted to say thank you so much for posting these! They've been saving my life taking this course, it really helps to try and figure out what went wrong with my code and how to try and go about fixing it.
