I might add that ifelse() is a vectorized function - is the operation you're
trying to perform vectorized?

Hi:
The first argument of ifelse is a logical statement that must evaluate to
either TRUE or FALSE. I'm guessing that you're using the append function
here, which is not a logical statement. Perhaps it would help if you
described what you wanted to do with a reproducible example to illustrate

More context would be useful, but my first guess is that you are
running into problems because both file and append are functions.
If you didn't explicitly set them to something else, R is using the
function.
What happens if you instead use:
filename <- "myfile.csv"
toappend <- FALSE
file(filename
I get an error message:
Error in file(file, ifelse(append, "a", "w")) : invalid 'open' argument
How do I resolve this?

Nope. You cannot just tack strings on the end of function calls. Try:
write.table(table_list, file= paste("file", x, ".

In order to use the extension csv, is the syntax:
write.table(table_list, file= paste("file", x, sep = "").csv, sep = ",") ?
Also I pretty much create a table by

Generally one would use an extension of .csv in that instance, and you
may need to move the column headers over one cell because the

My output is still a file object.
Wasn't that the point?

By using a sep argument of "," for write.table or using the pre-
packaged write.
