Converting text to pdf in R using rmarkdown

I am working on a function to convert a text file to pdf using R.

I am using rmarkdown.

There is already a script provided on SO to do it, which is as follows:

my_text <- readLines("YOUR PATH")
cat(my_text, sep=" \n", file = "my_text.Rmd")
render("my_text.Rmd", pdf_document())
file.remove("my_text.Rmd") #cleanup

This works perfectly.

I am trying to write it as a function.

My function is as follows:

my_text <- readLines(.txt)
cat(my_text, sep=" \n", file = "Report.Rmd")
render("Report.Rmd", pdf_document())
#file.remove("my_text.Rmd") #cleanup

However, when I run the function as convertTOtext(test.txt) [I am in the same directory as the text file], I get the following error:

processing file: Report.Rmd
output file:

! Undefined control sequence.
l.144 ``C:\Users

pandoc.exe: Error producing PDF

Rerun with Debug
Error: pandoc document conversion failed with error 43 In addition: Warning message:

What am I doing wrong?

Can someone help?



You need to check line 144 of your file. \ provides escape sequence to control various things suchs as tabs \t or newlines \n You can either convert your escape backslash to a literal one escaping it \\ or you can replace it with forwardslash /
