Hi all,
I'm trying to identify a particular digit or value within a vector of
factors. Specifically, this is environmental data where in some cases the
minimum value reported is "<" a particular number (and I want to manipulate
only these). For example:
x<-c("1","2","3","4","<1")
For a dataset that is hundreds or thousands of lines long, I'd like to find
or identify only those that have a "<" symbol (R automatically stores the
entire vector in factor format due to these symbols when it imports the
data-I don't mind converting if necessary). Eventually, I'd like to divide
the number in half for these cases, but I think I have that coding lined up
once I can just identify them from the stew.
I've exhausted help and net resources so far...
Thanks,
Ryan
