我有一個資料框
a = c("A","B","C")
b = c(12,13,14)
c = ("Great","OK","Bad")
df = data.frame(a,b,c)
我想用所有列的預期輸出列印出每一行：
A is 12 mins and it is Great
B is 13 mins and it is OK
C is 14 mins and it is Bad
我嘗試使用cat或 paste0 但它不能像我想要的那樣作業

joe NG，當您可以使用單獨的向量來獲得所需的輸出時，我不建議您創建資料框，但是可能有更多的方法來獲得所需的輸出。
a = c("A","B","C")
b = c(12,13,14)
c = c("Great","OK","Bad")
# create loop
d <- c(1:3)
# loop script to print output
for (x in 1:3){
print(paste0(a[x]," is ",b[x]," mins and it is ",c[x]))}

你可以使用sprintf-
with(df, sprintf('%s is %d mins and it is %s', a, b, c))
#[1] "A is 12 mins and it is Great" "B is 13 mins and it is OK"
#[3] "C is 14 mins and it is Bad"
如果你需要這個顯示的目的，在添加一個新行每行paste0有cat。
cat(with(df, paste0(sprintf('%s is %d mins and it is %s', a, b, c), collapse = '\n')))
#A is 12 mins and it is Great
#B is 13 mins and it is OK
#C is 14 mins and it is Bad
