Creating/Reading a complex string in R

Bogaso
Hi again,

Let say I have below string (arbitrary)

<html>
  <head>
    <script type="text/javascript"     <script type="text/javascript">
      mystatement('current', {'pac':['']});
      mystatement;


I want to pass above string to some R variable for further analysis.
So I have tried below :

String = '<html>
  <head>
    <script type="text/javascript"     <script type="text/javascript">
      mystatement('current', {'pac':['']});
      mystatement;'

It is not clearly working as I am getting below error :

> String = '<html>

+   <head>

+     <script type="text/javascript"     <script type="text/javascript">

+       mystatement('current', {'pac':['']});

Error: unexpected symbol in:

"    <script type="text/javascript"     <script type="text/javascript">

      mystatement('current"

>       mystatement;'

Error: object 'mystatement' not found

>


Any pointer how to create my string 'String' based on above would be
highly appreciated.

Thanks for your time.

Re: Creating/Reading a complex string in R

Richard M. Heiberger
your string opens with single quote ', and has a single quote ' in the middle.
R sees that as the end of the string.  You will need to escape the
interior ' with
\'
See ?Quotes
for details.

Try:

String = '<html>
  <head>
    <script type="text/javascript"     <script type="text/javascript">
      mystatement(\'current\', {\'pac\':[\'\']});
      mystatement;'


To embed a single ' mark in a string delimited by ' marks, you must
"escape" them by prefixing them with a back-slash \.

Re: Creating/Reading a complex string in R

Bogaso
Thanks for your pointer.

Is there any way in R how to replace " ' " with " /' " programmatically?

My actual string is quite lengthy, so changing it manually may not be
possible. I am aware of gsub() function, however not sure I can apply
it directly on my original string.

Regards,

​I guess your string value is in a file? And you'd like to update the file
contents. You didn't say which OS you're on. I'm a Linux person, and the
simplest for me would be:

sed -i -r "s/'/\\'/g" myfile.txt​ #note the \\ becomes a single \ in the
output. weird.

Or just edit the file in your favorite editor. In mine, vim, it would be
the command ":g/'/s/\\'/g" (the command is within the " marks).
You are correct that you could use gsub(). But you can't just paste your
string into an R program as is, as you have already seen. You'd need to put
it into a file. Then read that file into a program (perhaps an R program
using gsub()) to write the updated string to another file. Which contents
you could then cut'n'paste into your original R file.
something like:

#!/usr/bin/Rscript
#
files <- commandArgs(trailingOnly=TRUE);
#
for (infile in files) {
        x=readLines(infile);
        y=gsub("'","\\\\'",x);
        ofile=paste0(infile,".new");
        writeLines(y,ofile);
}

Hi,

perhaps you should simply read the content of a corresponding text
file? There's a simple way using the readr package. Using this
package, you can store the content of a whole file as a
single string. I haven't used it... but if you do choose this way, you
should investigate how it stores / mangages end-of-lines.

#install.packages(readr)
library(readr)
temp <- read_file('file.txt')

You can then process the string that is contained in the temp variable
as you wish to.

Re: Creating/Reading a complex string in R

In reply to this post by Bogaso
It was suggested to quote your string with *backticks* (` ... `) rather
than single quotes.

String <- `<html>
      <head>
      ...
`

That failed for me. The parser considered it a language object, an R name. Here's what I needed to do:

> string <- `"this string has both "'" and '"'`
Error: object '"this string has both "'" and '"'' not found
> string <- deparse(`"this string has both "'" and '"'`)
Error in deparse(`"this string has both "'" and '"'`) :
  object '"this string has both "'" and '"'' not found

But success with:


> string <- deparse(substitute(`"this string has both "'" and '"'`))

> string
[1] "\"this string has both \"'\" and '\"'"

With linefeed:

> string <- deparse(substitute(`"this string ...
+  has both "'" and '"'`))
> string
[1] "\"this string ...\n has both \"'\" and '\"'"

Forward-slashes are not going to have any desirable effect. They are not the R escape-character.

Best of luck. I do not think we yet know in what form this "string" exists at the moment. And it's not clear whether your use case requires keeping these lines all in one element of a character vector. Generally `readLines` and `scan` (and by extension all the read.* variants) wiill interpret the line-feeds as end of line.

Re: Creating/Reading a complex string in R

Jeff Newmiller
I think the whole premise of this question is flawed. If you want to work with this string as data,  then read it in from a separate file using readLines. If it is fixed data that you want to be part of your program, then invest the effort to escape the odd characters and be done with it. But using backticks is a bad idea because they ate not just another kind of quote.
