Subject: Changing Matrix Header
Hi Gundala,
try chopping off the top row like
newx<-as.matrix(x[2:dim(x)[1],])
OR
try changing it to a data frame...
new x<-data.frame(x,row.names=NULL)
#pretty sure its not row.names but there is probably an equivalent for
col.names
OR
look into ?read.table and specify header = F
Cheers, Si.
