Hi,
Look at ?cor.test, it does not give you the standard error, but it
does give you a confidence interval around the correlation coefficient
and a significance test (which is my best guess of what you are
probably looking to do with the standard error). You could also get
it out of a simple regression if the variables were z scored.
summary(lm(scale(y)~scale(x)))
Or since the formula is so simple you could just do:
sqrt((1 - cor(x, y)^2) / (length(x) - 2))
HTH,
Josh
