[R] lapply & subset

[christian schulz]

hello,
how is it possible  ( perhaps with lapply )
modifiy this so that  Q31.1 would be replaced with a loop which
select first column than second column, n column.........from configData 
etc.


x <- subset(configData, Q71 == 1 & Q31.1 ==1 , select = Q31.1) 
(dim(x)[1]/dim(configData)[1])*100

PseudoCode !?
for i in 1:ncol(configData) {
x <- subset(configData, Q71 == 1 & i ==1 , select = i) 
(dim(x)[1]/dim(configData)[1])*100
}

thanks for advance & regards,
Christian
