I have an R function from a package that I need to pass a file path as an argument but it's expecting a csv and my file is an xlsx.
I've looked at the code for the function an it is using read.csv to load the file but unfortunately I can't make any changes to the package.
Is there a good way to read in the xlsx and pass it to the function without writing it to a csv and having the function read it back in?
I came across the text argument for read.csv here: Is there a way to use read.csv to read from a string value rather than a file in R? This seems like might be part way there but as I said I am unable to alter the function.
