Hello,
I'm having some difficulty running Niels Waller's Maxcov Hitmax program in
the R console, and I was hoping you could provide me with some assistance.
When I attempt to run the analysis I receive the following message:
Indicators 1 3 & 2Error in if (del == 0 && to == 0) return(to) :
missi
Thanks, I have gotten past the problem with good old grep:
as.numeric(strsplit(st[grep("KGEG",st)],",")[[1]][4])
[1] 47.62139
The difficulty is trying to work with some complicated records that are
coded up to work with perl. But grep will work perfectly.
Thanks all,
Clint

I'm not sure I fully understand your problem, but maybe something like:
d <- strsplit(st, ",")
index <- sapply(d, function(x) x[[1]]) == "KGEG"
latitude <- sapply(d[index], function(x) x[[4]])

The rule is that everything is left associative except assignment and
exponentiation (and IF, for some reason). If in doubt, just remember
that it is the o

Well, I'm not surprised that it's syntactically valid, but I wouldn't

In mathematics, you would expect x = y not= z to mean
(x = y) and (y not= z).;
In R, it
