I have written the following function,
CSVDimension <- function(.csv) {
csv <- read.csv(.csv)
dimValue <- dim(csv)
print("The dimension of the dataset is:")
headValue <- head(csv)
print("The head of the dataset is:")
return(list(dimValue,headValue))
}
This function prints the dimension of a given dataset when we run,
> CSVDimension("path/to/file/dataset.csv")
My next step is to print this result on to a properly-formatted pdf file.
How can you write the output of the function CSVDimension
into a pdf file in R?
Assuming you have pandoc installed (and in your path), you can modify your function to
CSVDimension <- function(.csv, .pdf) {
csv <- read.csv(.csv)
dimValue <- dim(csv)
msg <- paste("The dimension of the dataset is:", paste(dimValue, collapse = " : "))
print(msg)
md <- sub("\\.pdf", ".md", .pdf)
cat(msg, file = md)
system(paste("pandoc -o", .pdf, md))
return(dimValue)
}
where .csv is the path to your csv file, and .pdf the path to the resulting pdf output.
