R version: 3.1.2 (2014-10-31)
RStudio version: 0.98.1091
MacOS X Yosemite v. 10.10.1

When I run the following in the console, all is well:
data(IlluminaHumanMethylation450kanno.ilmn12.hg19)

Yet, when I compile in my .Rmd file, in RStudio (knit to PDF), I get the 
following error:
Error in file(file, "rt") : cannot open the connection
Calls: <Anonymous> ... withVisible -> eval -> eval -> read.delim -> read.table 
-> file
Execution halted

From what I have read, this could be alleviated by pointing the the source file 
for data(IlluminaHumanMethylation450kanno.ilmn12.hg19) as opposed to 
LazyLoading with the data() function.  Yet, I’m not sure how to work around 
this. (This is my first R project ever) The 
data(IlluminaHumanMethylation450kanno.ilmn12.hg19) is just loading an 
annotation file from library(IlluminaHumanMethylation450kanno.ilmn12.hg19), and 
I’m not sure of the file type the data are stored under (.txt, .csv, etc). 

Thanks in advance!

Molly
