Expanding slightly on Ista's answer, this may help if you are using Windows and want the symbol to appear in the console or in plots
> beta <- intToUtf8(0x03B2) # or intToUtf8(946) > a <- 0:9 > names(a) <- paste0(beta, a) > a β0 β1 β2 β3 β4 β5 β6 β7 β8 β9 0 1 2 3 4 5 6 7 8 9 > plot(0:9, 0:9, typ="n") > text(0:9, 0:9, names(a)) You just have to figure out the utf8 code for the symbol you want. Windows Character Map works for this and lets you insert the code directly as Ista did, or any of the various web pages listing the codes. ------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of John Sorkin Sent: Sunday, July 5, 2015 6:58 PM To: bgunter.4...@gmail.com; istaz...@gmail.com Cc: r-help@r-project.org Subject: Re: [R] Greek letters in column titles.

But maybe this will get you started/prove useful. Just beware. 1. First of all, as Ista said, this can be done, but it is heavily system dependent as to how. Basically I think you want access to UTF-8 encodings, which any modern OS should support, but that access is dependent on your system. 2. It also depends on where you want to display the results -- on screen, into a pdf, or ? . 3. See also The man pages on ?unicode and ?iconv , as these may also be relevant.
