I want to print

in the easiest way using 'for'. similarly,

   #
    #
     #

I want to print this in similar structure with code above

what I tried :

for(i in 1:5){
  cat(("*"*i), "/n")
}

but it's wrong because it's non-numeric argument.

CodePudding user response：

You're almost there! just change cat(("*"*i), "/n") to cat(rep(" ", i), "\n"). Use rep and use \ instead of /.

> for(i in 1:5) {
    cat(rep(" ", i), "\n")
    }

CodePudding user response：

You could use rep

for(i in 1:5){
print(rep('*', i), quote=FALSE)
}
