逗号分隔字符串分割

Question

我想我用下面的代码

a<-c("1,2,3","344") 

转换这个矢量列到这个

a<-c("1","2","3","344") 

：

a<-c("1,2,3","344") 

b<-strsplit(a, ",") 

c<-sapply(b, paste0, collapse=",") 

但我回到原始矢量：

c<-c("1,2,3","344") 

任何帮助，将不胜感激。

感谢，

Answer 1

尝试：

a <- c("1,2,3","344") 
scan(text = a, sep = ",", what = "") 
# [1] "1" "2" "3" "344" 

Answer 2

该解决方案是相同的一个关于我的评论：

a <- c("1,2,3", "344") 
b <- unlist(strsplit(a, ",")) 
b 
[1] "1" "2" "3" "344"
