Dear list;
How can I speed up the run of following code (illustrative)
#========================================================================
con<-vector("numeric")
for (i in 1:limit)
{
if(matched data for the ith item found) {
if(i==1) {con<-RowOfMatchedData } else
{con<-rbind(con,matchedData)}
}
}
#========================================================================
each RowOfMatchedData contains 105 variables, when "i" runs over 10^7
and the data container "con" get large enough, the codes get extremely
slow, I know this is a working memory problem (2GB only), is there
anyway to circumvent this problem without dicing and slicing the data.
