I have recently been using the R program and encountered a recurring problem. I have been trying calculate the correlation of a 16 column table. Everytime I type in cor(test), where test is data that I uploaded into R using the read.table function, I get an error:

Error in cor(test) : missing observations in cov/cor In addition: Warning message:
In cor(test) : NAs introduced by coercion

Can anyone tell me what I am doing wrong and what I need to do to correct this?

Also I intend on running the T-Stats, P-Stats, Information Coefficient and Information Ratios once I get the correlation table calculated. If you know which packages, if any, have are able to calculate this, that would be helpful.
