随着mclapply()所有发出的警告似乎得到抑制:
library(multicore)
mclapply(1:3, function(x) warning(x))
[[1]]
[1] "1"
[[2]]
[1] "2"
[[3]]
[1] "3"
同时lapply会给:
lapply(1:3, function(x) warning(x))
[[1]]
[1] "1"
[[2]]
[1] "2"
[[3]]
[1] "3"
Warning messages:
1: In FUN(1:3[[3L]], ...) : 1
2: In FUN(1:3[[3L]], ...) : 2
3: In FUN(1:3[[3L]], ...) : 3
有关如何避免丢失警告的任何提示？
