Large print output #98

Some examples have text output that greatly extend far to the right. While it works online (scroll bars), it may not work for a book.

How would you solve this (appart from manually copying and rearranging the output)?

schloerke commented 3 years ago

TIL...

You can set an option (probably in a hidden chunk) to limit the width:

str(letters)
#>  chr [1:26] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "k" "l" "m" "n" "o" "p" ...
options(width = 40)
str(letters)
#>  chr [1:26] "a" "b" "c" "d" "e" "f" ...

According to https://bookdown.org/yihui/rmarkdown-cookbook/text-width.html, this does not work with my case. I tried with the proposed alternative (listings) but the pdf output is even worse.

schloerke commented 3 years ago

Ok. Might be worth setting a width option anyway for str() output. Otherwise, best that I know how to do is to leave it as is.

Currently working on it. There is no easy way currently but I found some tricks thanks to your code_chunk() idea.
