How to resolve the following error: (list) object cannot be coerced to type 'double'
Have you read (relevant sections) of "An Introduction to R" to gain some basic understanding of how R works? If not, please do so before further posting. Briefly, Var is a data frame and rcorr wants a matrix. -- Bert

Hello,
I'd like to test a significance of two variables in their correlation using
rcorr, which gave me an error of format incompatibility.
Below are the lines that I typed in the R window and let me know if anyone
knows how to resolve this.
Var=read.csv("03apr10ab_corr_matrix_in_overlaps.csv",header=F)
colnames(Var)=c("D Prime","T statistics")
D Prime T statistics
1 1.7234e-01 4.926800
2 1.4399e-01 2.892000
3 1.4626e-01 2.642800
4 3.5147e-02 1.112400
5 5.8957e-02 2.723700
rcorr(Var, type="pearson")
Error in storage.mode(x) <- if (.R.) "double" else "single" :
(list) object cannot be coerced to type 'double'
