Hi Gianni, First the chide, you are asking a general (very beginner) R question on the Geospatial Special Interest Group mailing list, which isn't the right list for your question. The closest to the correct list is R-Help, but this is really something one learns from books on R, which there are a number of, and often available in online in PDF (start with An Introduction to R, http://cran.r-project.org/doc/manuals/R-intro.pdf). Now the answer to your question: BestResult_R <- newData[newData$result == max(newData$result), ] Dan Putler On Tue, 2009-10-13 at 16:59 -0700, gianni lavaredo wrote:thanks for help, I have a data.frame "newData" with 7 columns and 91 rows. i wish to find the row in the second column "X" with the max value and save all 7 values (=all columns) in a new data.frame # max value result for row Max.Result <- max(newData$result) select the row with the max value row <- which(Max.Result == max(Max.Result )) BestResult_R <- newData[row,] but I have a same problems to set right the code. thanks Gianni [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
