[R] JPEG command not responding to size options

R 3.2.0 OS X Colleagues I have a script that has been unchanged for years but I just noticed a difference in the output. A minimal example is: jpeg(file="xxx.jpeg", width=4, height=2, unit="in", pointsize=12, bg="white", res=150, quality=100) plot(1) graphics.off()

[R] Missing axis labels

R 3.2.0 OS X This is a general question, not specific to OS X. Colleagues Often, one or more values on an axis will be omitted, presumably in order to prevent overlap. However, there are situations where I would like to override that omission. Sample code: pdf("labels.pdf", width=3,

[R] Failure to execute R CMD SHLIB successfully

R 3.1.2 Windows 7 Colleagues I am working with c code that reads sas7bdat files into R. I have been successful in compiling and running the code in both OS X and Windows. Recently, the author of the c code added code that calls iconv.h (in order to convert encodings). Using the new version

[R] Accessing objects manipulated in a function

R 3.2.4 OS X and Windows Colleagues, I distribute some code to co-workers and I am trying to simplify their task. The issue is as follows: 1. The code automates an extensive set of processes. Many of the steps are standardized. However, some of the steps may require that users write snippe

[R] Syntax for error messages

R 2.15 OS X and Windows Colleagues, I am running a lengthy R script (> 20K lines of code) within a GUI build in RealBasic. There are rare instances in which an error is triggered in R. I am trying to trap these based on their syntax. I have identified three general formats for error message

[R] rainbow producing colors that do not differ sufficiently

R 2.15.2 OS X Colleagues, I often use rainbow to select colors. I encountered a surprise with rainbow(11). It yielded three greens (in positions 4-6). The first two of these are quite similar. The man pages suggest that this might be the case: equispaced hues in RGB space tend to c

[R] Understanding contents of packages

Colleagues During the transition to R3.0.0 (OS X), one of the packages that I used -- SASxport -- did not work until I used the "type=source" option in install.packages. This led to an adventure: 1. I downloaded the package source:SASxport_1.2.4.tar.gz 2. in the
