[R] exporting character vector to text files

[Vladimir Eremeev]

Use get() instead of eval().
And, probably, some arguments are missing in call to paste(). 
Maybe, extension?

That is, 
for(i in test) 
  write.table(get(i),file=paste(i,"txt",sep="."),row.names=FALSE,sep="\t")

If you want file names matching exactly names of your matrices, and being
without extension,
you don't need to call paste() at all:

for(i in test) 
  write.table(get(i),file=i,row.names=FALSE,sep="\t")
