l1 <- list(a=list(1:4),b=list(1:6))
l2 <- list(a=list(1:4),b=list(1:6))
After performing l1+l2, the error is following
non-numeric argument to binary operator
To solve such errors, we can use lapply() function to go through each list simultaneously.
lapply(seq_along(l1),function(i)
unlist(l1[i])+unlist(l2[i]))
[[1]] a1 a2 a3 a4
2 4 6 8
[[2]] b1 b2 b3 b4 b5 b6
2 4 6 8 10 12
