Error in sum(x[-1][x[-1] > 0]) : invalid 'type' (character) of argument:
I changed the id=c(100,101) in myDF, it worked. are there any way to have
this working if the id=c("a10","a20")?
doit <-
function(x)c(sum_LK_positive=sum(x[x>0]),sum_LK_negative=sum(x[x<0]))
cbind(myDF, t(apply(myDF[-1],1,doit)))
