[R] Averaging within a range of values

Hello,

I believe this works

res <- NULL
for(i in 1:nrow(df1)){
	brk <- df1[i, 2:3]
	ix  <- df2$Pos >= brk$Start & df2$Pos <= brk$End
	res <- rbind(res, apply(df2[ix, -1], 2, mean))
}
res

It's not very pretty but since the ranges can overlap, I'm not finding
anything prettier (without a loop).
