Hi. I tried running the following code. I don't understand the error.
mydata <- read.table("C:/dataForR/radiology/wordFrequencies.csv",
header=TRUE, sep=",")

mydataN<-mydata[,-923]
> dim(mydataN)
[1] 982 923
cor(mydataN)

Error in solve.default(cv) :
Lapack routine dgesv: system is exactly singular

[1] 982 924
The second to last column was also not numeric and so I did
