[R] error about MCA

Probably because you have defined all of the variables as
supplemental. These will then be estimated from the other variables,
but there are no other variables.

Subject: [R] error about MCA

Hi,all:
I want to perform multiple correspondance analysis via
MCA{FactoMineR}.
The data is in the attachment.

My code:
dat<-read.delim("e:\\mydata.txt",header=T)
MCA(dat,quanti.sup=7,quali.sup=1:6)
Error in `[.data.frame`(tab, , i) : undefined columns selected
 
My question:
Why does the error happen?
 
Many thanks.

Best.
