Hello,
I have some data file, say, mydata
1,2,3,4,5,6,7
3,3,4,4,w,w,1
w,3,6,5,7,8,9
4,4,w,5,3,3,0
i want to replace some percentages of "mydata" file in to NAs for those values
that are NOT w's. I know how to apply the percentage thing here but don't know
how to select those values that are not "w"s. So far, i was able to do it but
the result replaces the w's also which i do not want to.
Here is my code that i tried to exclude those w's(within my short codes)
ifelse(mydata[sample,var] != 'w',mydata[sm,var]<-NA,'w')
Can any one help please?
Thank you
Daniel
