Re: [R] [Rd] italic font on cairo devices in R 3.4

Hi Ilia, You may want to have a try of the showtext package (https://github.com/yixuan/showtext). Below is a quick example: library(showtext) showtext.auto() pdf("test.pdf") ## Use the "sans" font family provided by the showtext package ## font == 3 means italic font face plot(1, xlab = "Unicode

Re: [R] Factor vs character in a data.frame vs vector

Thanks Marc. It never occurred to me that I would need a ""stringsAsFactors" expression in a data.frame.  I could have sworn I never did before when mocking up some data but clearly I was wrong or there has been a change in R v. 3.4.1 which seems unlikely. On Friday, July 7, 2017, 10:37:29 AM

Re: [R] [Rd] italic font on cairo devices in R 3.4

Interesting. I did not have the package installed, but I did at some point extract Helvetica from some MacOSX font files and R was using that just fine until 3.3. This is how the plot looks in 3.4 (still using Helvetica): https://ptpb.pw/HikX.pdf . After removing Helvetica, installing the ttf-m

Hi Ilia, I'm running Arch Linux, R 3.4.0. Here's my test.pdf from your minimal example: https://ptpb.pw/HxsA.pdf It doesn't look pixelated to me... Here's a post that I wrote when I solved my last font problem in R, almost 2 years ago: https://stackoverflow.com/a/40940331/5087283 I had to ins

[R] Factor vs character in a data.frame vs vector

This is not  serious problem but I just wonder if someone can explain what is happening. The same command within a dataframe is giving me a factor and as a plain vector is giving me a character.  It's probably something simple that I have read and forgotten but I thought I'd ask. Thanks #==

[R] R loop function in Tableau

Hi R helpers, I hope this email finds you well. I am having trouble with R loop function in Tableau. Please see the attachment of a simple dataset. The problem is to test whether the value of columns is match. Because Tableau do not have iteration function, I coded “if statement” in
