R code to convert a vector of ints to common width strings by prepending 0's

toStringVectorPrependZeros

# \fn
# \brief Get common width strings from a list of numbers
# \param 'numbers' is an integer vector of numbers
# \return A vector of strings normalized to the same width
#
# Example: 
#    inputof: 5,6,7,8,9,10,11
#    outputs: 05,06,07,08,09,10,11

toStringVectorPrependZeros <- function(numbers)
{
    width <- nchar(toString(max(numbers)))
    vec <- formatC(numbers, width=width, flag="0")
}

id = 1:332
fixedIDs <- sprintf("%03s", id)

I see what you are getting at, good point, UPDATED
