Hello,
could someone help me with this problem?:
I would like to create a latex-script inside of a character vector in order
to being able to compilate it within latex in the end.
if i try the following commands:
l1<- "Hello world"
latexscript<- paste("\c",l1,"\c")
... I get an error message. I think the problem is that r sees \c as a
command.
How can I get
"\c Hello world \c"
as a result without getting the error message?
Here's the long answer:
R uses \ as an "escape character", which is different from the way LaTeX
uses it. The string "\n" contains a single character (a newline
character. When you say "\c", the parser thinks you are asking for a
single character which is written as \c, but there isn't one, so you get
the error message.
To put the characters \c into a string, you need to escape the
backslash, i.e. use "\\c". That's a two character string. It will
print as "\\c" using print(), but if you use cat() you will see the
actual characters \c.
The short answer is:
latexscript <- paste("\\c", l1, "\\c")
cat(latexscript, "\n")
