Dear R
I'm trying to do a correlation matrix for some variables I have.
Unfortunately there are some NA entries for some of the variables I tried the following
cor(sleep[c("logbw", "logbrw", "SlowSleep", "ParaSleep", "loglife", "loggest")])
but it told me
Error in cor(sleep[c("logbw", "logbrw", "SlowSleep", "ParaSleep", "loglife",
: missing observations in cov/cor
How can I get R to conduct a correlation matrix for this data set??

See ?cor. I think you want:
cor(sleep, use = "complete.obs") # or "pairwise.complete.obs"
(please read the posting guide, which would tell you to use an informative subject line and also point you to the help files)
