Why RStudio source pdf output difference with R prompt?

Question

I get correct output of the following code for Rscript code.r but damaged file when running RStudio source in the minimal project, which I do not understand. Code

pdf("test.pdf")
plot(iris)

There are quite big differences in Details of those two sessions listed following for RStudio vs R prompt. So some setting of RStudio must be wrongly configured.

1. locale: 9 vs 11 things
2. namespace: 1 vs 5 things

Answer 1

This code works in RStudio where RStudio requires dev.off() for some reason

pdf("test.pdf")

dev.off()
