R: Is there a maximum number of columns allowed in a list

I tried to expand a table with new values but it failed at the 100 somethings' column. So I did a test with the following code. Only the first 100 columns are added. Is this R's limit or can I bypass it somehow?

x <- list()
x$c1 <- NA
x$c2 <- NA
x$c3 <- NA
x$c4 <- NA
x$c5 <- NA
x$c6 <- NA
x$c7 <- NA
x$c8 <- NA
x$c9 <- NA
x$c10 <- NA

There is no such limit. Try names(x) and you'll see all the columns are there. Another good function for inspecting objects is str(x) but this output is truncated for such a large object. I don't use View() but it either has a limit (not apparent from the help page) or it's just clunky.
