逗號分隔字符串分割

Question

我想我用下面的代碼

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

轉換這個矢量列到這個

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") 

任何幫助，將不勝感激。

感謝，

Answer 1

嘗試：

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

Answer 2

該解決方案是相同的一個關於我的評論：

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