Hi Ramya, You're almost there. Just specify that you want to order all the data set based-on the third column. Here is an example: # Data information=data.frame( geneset=letters[1:7], chromosome=1, hit=c(51,24,30,17,35,55,61)) # New data information[order(information[,3],decreasing=TRUE),] HTH, Jorge On Wed, Nov 5, 2008 at 2:02 PM, Rajasekaramya <ramya.victory@gmail.com>wrote:> > Geneset_name #Chromosome #Hit_in_Biomart > original_geneset_len Missing.genes > [1,] "AGUIRRE_PANCREAS_CHR12" "1" "51" > "59" "8" > [3,] "AGUIRRE_PANCREAS_CHR9" "1" "24" > "24" "0" > [4,] "AGUIRRE_PANCREAS_CHR1" "1" "30" > "31" "1" > [5,] "AGUIRRE_PANCREAS_CHR18" "1" "17" > "17" "0" > [6,] "AGUIRRE_PANCREAS_CHR7" "1" "35" > "48" "13" > [7,] "AGUIRRE_PANCREAS_CHR8" "1" "55" > "61" "6" > > Above is a dataframe information. > > i need to sort the entire dataframe based on the 3rd colum. in decending > order. > > I tried using order > > information[order(information[,3])] but it gives me only the ordered first > coulmn that too i am not sure that it really works. > > Kindly let me know with any suggestions. > > Regards > Ramya > > > -- > View this message in context: > http://www.nabble.com/Sort-help-tp20346314p20346314.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >[[alternative HTML version deleted]]
