Urgent Help with R calculation correlation coefficient

Hi,

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


[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)

[/code]

i get error x must be numeric..

can anybody help me.

thanks in advance
