Question

I am sending a json array by POST to an R script. The array looks like this:

POST$samples=
 {"DIW blank":["23.36"],
  "DA-f 1000 20081118":["6.31"],
  "1294 RM DA Biosense Nov 2008":["6.28"],
  "1334 RM DA Biosense Nov 2008":["6.28","22.84"],
  "1422 RM DA Biosense Nov 2008":["6.29"]
 }

When I convert that from json in R, I get this list:

$`DIW blank`
[1] "23.36"

$`DA-f 1000 20081118`
[1] "6.31"

$`1294 RM DA Biosense Nov 2008`
[1] "6.28"

$`1334 RM DA Biosense Nov 2008`
[1] "6.28"  "22.84"

$`1422 RM DA Biosense Nov 2008`
[1] "6.29"

What I’d like is for all the number vectors to actually be numbers. Do I have to foreach through the list with as.numeric, or is there an easier way?

This is the one line bit of code that joran was (perhaps) thinking about:

lis2  <- lapply(lis1, as.numeric)
