You did not show the error message you got from that failing command.
I get:
> x <- 1
> save("x", file="C:\am\myfiles\ProjectA.RData")
Error: '\m' is an unrecognized escape in character string starting ""C:\am\m"
> "C:\am\myfiles\ProjectA.RData"
Error: '\m' is an unrecognized escape in character string starting ""C:\am\m"
which is intended to make it clear that "\m" is not legal in a string. If,
instead of 'escape'
it said 'backslashed character', would you have understood that the problem is
with how backslashes are represented in R strings?
