Problems executing cor(dataset) function in R 2.11.0 for OS X ( It works fine in R 2.10.1)
...icate John M. Quick's example for correlations between multiple variables posted on: http://rtutorialseries.blogspot.com/2009/11/r-tutorial-series-zero-order.html with R 2.11.0 (GUI 1.33) using my MacBook Pro with OX X 10.5.8 I got the following error message > datavar<-read.csv("dataset_readingTests.csv") > cor(datavar) Error in cor(datavar) : 'x' must be numeric The funny thing is that when I tried to do the same example using R 2.10.1, it worked fine. Any ideas regarding how to solve this problem? Many thanks in advance, Ruben
