Hello, Sorry if this is somewhere in the archives but i couldn't find it. I am using the funtion cor() and inputting a large matrix with a column of 0, for which i get NA's for. I'm looking for a way to overcome that divide by 0 error btw but my real issue is this: I specify the method as pearson but the error messages always say kendall ex) > read.csv("ncatest.csv", header = FALSE, sep = ",", dec=".")->ncatest > ncatest<- ncatest[,-1] > rownames(ncatest2)<- ncatest[,1] > ncatest2<-as.matrix(ncatest2) > > dim(ncatest2) [1] 10482 11 > cornca<-cor(ncatest2, method="pearson") Warning message: the standard deviation is zero in: cor(x, y, na.method, method == "kendall")
I would like to confirm that i am using the metric I specified and that its not defaulting to kendall for some weird reason. Thanks for any assistance.
