[R] Rprintf will not build in my C++ compiler

I have searched through the threads and "Rprintf" causing a build error dosen't seem to be a problem for anyone else. And I've read through "R Extensions" and "An Introduction to the .C Interface to R" and there doesn't seem to be any troubleshooting for my problem. My code is straight from "An

I'm well aware these are not errors, I guess I miss-wrote. I understand your concern. Thanks for passionately looking out for my well being, you saved my life. My variable has about 10,000 elements and sometime for the first 100 to 500 elements there is lots of 0's, so I end up with lots of NA/N

[R] Dividing by 0

I'm trying to calculate the percent change for a time-series variable. Basically the first several observations often look like this, x <- c(100, 0, 0, 150, 130, 0, 0, 200, 0) and then later in the life of the variable they're are generally no more 0's. So when I try to calculate the percent c

[R] Summary Stats (not summary(x))

I'm looking for a function that lists a few summary stats for a column (or row) of data. I'm aware of summary(x), but that does not give me what I'm looking for. I'm actually looking for something that is very similar to the descriptive statistics tool in excel; i.e. Mean, Std. Error, Std. Deviat
