Dear R-Users, I have a csv file that has NA tokens and these tokens are perfectly good values that need not to be converted to NA by read.table(). I tried to prevent the conversion by specifying the na.strings arg., but this seems to only add to the list of NA strings, not substitute.
> system("cat foo") system("cat foo") 1 foo 2 NA > read.table("foo", na.strings="foo") read.table("foo", na.strings="foo") V1 V2 1 1 NA 2 2 NA This is R1.6.0 on Linux. What did I do wrong?
