Question

I have this code:

x <- rnorm(10)
print(x)

is returning as output:

[1] -0.67604293 -0.49002147  1.50190943  0.48438935 -0.17091949  0.39868189
[7] -0.57922386 -0.08172699 -0.82327067  0.07005629

I suppose that R is having a limit of characters per line or something and that is why is splitting the result in 2 lines. I am building a service based on the output of R.

What should I do in order to get it in one line?

Answer 1

Than it is better to tell R to output things in a way that will be convenient to your wrapper; check out string functions like paste(), sprintf() and push the result into output with cat(); for instance putting numbers in a column could look like:

x<-rnorm(10)
cat(paste(x,collapse="\n"),"\n")

what outputs just:

0.889105851072202
0.86920550247321
0.817785758768382
