r - knitr: object cannot be found when converting markdown file into html

Question

Hi I am using R studio and the "knitHTML" button to convert my Rmd file into a html file. However, even thought the code runs fine, when using knitHTML it cannot find any of my objects previously created:

## Error: object 'cbt_2010' not found

however if I type cbt_2010 at the terminal - it is there. Bascially knit cannot find any of the objects in the workspace.

what am I doing wrong? it just seems any data produced in each chunk is lost in memory when using knit!

As already mentioned by @BenBolker , you can use knit2html( Note that it is different from the Rstudio button, Rstudio use its own function to process document) from knitr:

 x <- 10
 writeLines(c("# hello markdown",
          "```{r hello-random, echo=TRUE}", 
               "rnorm(x)", "```"), ## note the use of x
 "test.Rmd")
 library(knitr)
 knit2html("test.Rmd")
