R help - Mar 2015 - Mann-Kendall test for many independent columns data set at a time

I am analyzing trend test using Mann-kendall monotonic trendtest for 10,368
independent grid cell, each grid has 34 years dataset. ?I supposed to find
Kendall ?tau? for each gridcell (each grid has 34 years data). The data is
arranged in column wise (Iattached? part of the grid dataset? as a sample).

To find Kendall tau, I wrote R script as:


desta<-read.csv("rainfall.csv",header=T, sep=",")

require(Kendall) 

MK<-function(y) {

??????? ?nc<-ncol(y)

?????? MannKendalltau<-numeric(nc)

??????? for(i in 2:nc){

? ? ? ? ? ?MannKendalltau[i]<-MannKendall(y[,i])

?????????? }

????? ??????MannKendalltau

??? }

??? MK(desta)


The result displayed both ?tau??and ?2-sided pvalue?. ?But, I wantonly ?tau?
value that is printed in organized way. Anyone can tell me how can Iget orderly
printed ?tau? value ?for allgrid cells at a time. ???


Thank you for your help in advance,Desta WodeboTU-DresdenGermany?
