Do you always use row.names=F in write.csv? Changing the default values inside R (base) functions

Question

Couldn't see a solution online but I thought this might be quite common.

• with write.csv I basically always have the argument row.name set to F. Is it possible to run a line once and update the default value of the argument for the rest of the session?
• I tried paste <- paste(sep="") which ran and returned no error but seemed to do nothing (and didn't destroy the paste function). This is another one, I always set sep="" with paste...
• like I always have exclude=NULL when I am using table so I can see the N/A values.

EDIT: So, I'm looking for a solution that will work for multiple functions if possible: paste, write.csv, table and other functions like these.

Answer 1

paste <- paste(sep="") puts the output of paste() into an object named "paste". You would need to do something like this instead.

paste <- function (..., sep = "", collapse = NULL) {
  base::paste(..., sep=sep, collapse=collapse)
}

You can also look at the Defaults package for this sort of thing, but it doesn't currently work for two of your examples.
