I am trying to calculate correlation coefficient for gene expression data.

Tab delimited file looks like this

Id v1   v2    v3
df 56   90    45
gh 87   98    78
ty 89    78    67

I used this code


gse20437 <- read.csv("C:/Users//Desktop/data/GSE20437_matrix.txt",header =
TRUE, sep = ",", strip.white = TRUE)

gsecor <- cor(gse20437, method ="pearson") or

gsecor <- cor(gse20437)


i get error x must be numeric..

can anybody help me.

thanks in advance
