I'm using RStudio to run some data analysis and would like to use the package sqldf. Once I require the package, I get the output bellow:

Loading required package: sqldf
Loading required package: gsubfn
Loading required package: proto
Could not load tcltk. Will use slower R code instead.
Loading required package: RSQLite
Warning message:
In doTryCatch(return(expr), name, parentenv, handler) :

My sessionInfo() is as follows:

other attached packages:
[1] sqldf_0.4-10 RSQLite_1.1-2 gsubfn_0.6-6 proto_1.0.0

Also,

tcltk
TRUE

How can I solve this?

I don't know if you solved the problem but I'll write you the solution that worked for me (found here https://support.bioconductor.org/p/31750/).

You need to go here http://cran.r-project.org/bin/macosx/tools/

and get the tcltk-*.pkg from there. After installing the package, it won't appear any warnings when you load the sqldf library.
