r - 用 R 在字符之间插入逗号

Question

样本数据:

data <- round(rnorm(10,100000,10000),-1)
char <- as.character(data)

我想在字符之间使用逗号:

[1] "104350","108800","101320","94140","102260","89340","114220","105830","111270","85300"

我试过 paste()还有 read.table & read.lines与 sep=","没有成功。

Answer 1

你追求的是审美而不是这个答案的功能:

cat(paste0('"', paste(char, collapse="\", \""), '"'))

## "115030", "118990", "72910", "121050", "93820", "119310", "110370", "100590", "98220", "118200"

储藏:

store <- paste0('"', paste(char, collapse="\", \""), '"')
