Hi all,
Is there a function to check if a particular value is contained in a
vector? I've looked at grep in the hope that I could use a Perl-like
syntax, but obviously it's different...
I'd like to do something like:
y <- c("a","b","c")
if("a" in y)
{
# "a" is not in y
}
Also, is there a way to generate character sequences similar to numeric
sequences, e.g. something like "A":"J" ? I remember having seen a
command doing this somewhere, but can't find it anymore
Thanks
Pascal
