build_home(): Error in file(con, "r") : cannot open the connection

Debugging:

Caused by render_rmd():

render_rmd(pkg, input, "index.html", depth = depth, 
      data = data, toc = FALSE, strip_header = TRUE)

Quitting from lines 18-20 (README.Rmd)
Error in file(con, "r") : cannot open the connection

Problematic lines in README.Rmd (first R code chunk in README):

description <- readLines("DESCRIPTION")
version <- gsub(" ", "", gsub("Version:", "", 
                grep("Version:", description, value = TRUE)))

I don't understand the problem

When calling build_home(), I get the above mentioned error.

It is caused by

version <- gsub(" ", "", gsub("Version:", "", 
                grep("Version:", description, value = TRUE)))

I did not find a solution and just used a direct assignment version <- "0.1" instead of trying to gsub() it from the DESCRIPTION file. The error is only thrown by build_home() and not when normally knitting README.Rmd.

Closing since you seem to have a solution.
