Title Body

I am running R version 2.15.3 with RStudio version 0.97.312. I have one script that reads my data from various sources and creates several data.tables. I then have another r script which uses the data.tables created in the first script. I wanted to turn the second script into a R markdown script so that the results of analysis can be outputted as a report. I do not know the purpose of read_chunk , as opposed to source . My read_chunk is not working, but source is working. With either instance I do not get to see the objects in my workspace panel of RStudio. Please explain the difference between read_chunk and source ? Why would I use one or the other? Why will my .Rmd script not work Here is ridiculously simplified sample It does not work. I get the following message Error: object 'z' not found Two simple files... test of source to rmd.R x <- 1:10 y <- 3:4 z <- x*y testing source.Rmd Can I run another script from Rmd ======================================================== Testing if I can run "test of source to rmd.R" ```{r first part} require(knitr) read_chunk("test of source to rmd.R") a <- z-1000 a ``` The above worked only if I replaced "read_chunk" with "source". I can use the vectors outside of the code chunk as in inline usage. So here I will tell you that the first number is `r a[1]`. The most interesting thing is that I cannot see the variables in RStudio workspace but it must be there somewhere.
