When it comes to R blogging I’m a complete newbie. So I’m still struggling with the technical details.**A Distant ObserveR**, and kindly contributed to R-bloggers].

Part of the process is prettifying the code snippets. One of the standard ways of doing this involves copy-and-paste-ing the R code into the Pretty R syntax highlighter.

While assembling the bits to do the posting programmatically I wrote a function that replaces the copy-and-paste part.

Now here’s the function prettified by itself:

prettyR <- function(file) { require(RCurl) require(XML) Rcode <- readLines(file) Rcode <- paste(Rcode, collapse="\n") # assemble the parameters for the http POST to the Pretty R web site URL <- "http://www.inside-r.org/pretty-r/tool" parameters <- list( op = "edit-submit", form_id = "pretty_r_tool_form", code_input = Rcode ) # send the http POST request rawHTML <- postForm(URL, .params = parameters) parsedHTML <- htmlParse(rawHTML) # find the node prettified <- getNodeSet(parsedHTML, "//div[@class='form-item']/textarea")[[1]] prettified <- xmlValue(prettified[[1]]) return(prettified) }
