Hello!

First time posting here:

Here is my code:

x <- c(1:22)
finaloutput=cidrm=NULL
finaldiversityoutput=diversitym=NULL

diversityinfo=read.table("Diversity_info.txt", header=T, sep="\t",
row.names=NULL)
attach(diversityinfo)
diversitynr=nrow(diversityinfo)
diversitytemp <- matrix(0,nrow=diversitynr,ncol=1)

for(j in 1:length(x))
{
diversitym=read.table(paste(paste("Div-Chr",x[j],
sep=""),"_corr.txt",sep=""), header=T, sep="\t", row.names=NULL)
attach(diversitym)
diversitytemp <- cbind(diversitytemp,diversitym)
print(paste(paste("Diversity-Chrom",x[j], sep=""),".txt",sep=""))
print(dim(diversitytemp))
}

I am essentially trying to combine several tab-delimited text data files
together into one big file.

I recently upgraded to R 2.2.0.  I now get multiple error messages of
the form:
The following object(s) are masked from diversitym ( position 4 ) :

         X X.1 X.2

I searched on "masked" and read the manual about "conflicts" but I don't
really understand what the issue is.  I didn't get this error message,
using the same code with R 2.1.0.  Can somebody help (I'm not a
programmer).
