Print multiple variables in one line in r-CodePudding

I have a dataframe

a = c("A","B","C")
b = c(12,13,14)
c = ("Great","OK","Bad")

df = data.frame(a,b,c)

I want to print out every row with all the column Expected output:

A is 12 mins and it is Great
B is 13 mins and it is OK
C is 14 mins and it is Bad

I tried to use cat or paste0 but it doesnt work as what I want

joe NG, i wouldnt suggest you create a data frame when you can use separate vectors to get the desired output, however there could be many more ways to get you desired output.

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]))}

CodePudding user response：

You may use 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"

If you need this for display purpose with each row in a new line add paste0 with 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
