I have created a 5 column matrix of the data and here have shown the
variable names of each column.  I do not understand the error message given
when I try to run the cloud function  Thank you in advance for your help.

> V1<-data[,1]
> V2<-data[,2]
> V3<-data[,3]
> V4<-data[,4]
> Gender<-data[,5]
> library(lattice)
> cloud(V1~V2*V3)
Error in extend.limits(range(as.numeric(z), finite = TRUE)) :
  (list) object cannot be coerced to type 'double'
