Hi,
One more question, I try the princom with demo data, and it showes correct result.
But while I try my data by this command:
setwd("D:/Documents and Settings/bmb.trainee/My Documents/R")
test <- read.csv("test1.csv",header = T)
head(test)
test1.pr <- princomp(test,cor=TRUE)
it always show Error message as below:
Error in cov.wt(z) : 'x' must contain finite values only
What is this mean...
my data formate as below:
PoHGT DTF DTM
1 9.0 53 69
2 8.3 43 76
3 7.2 43 69
4 5.6 43 69
5 7.5 40 68
6 7.6 43 69
