Colleagues I am executing a length script in R (20K lines). At one point, it returns: > Loading required package: tcltk > Loading Tcl/Tk interface ... done > Loading required package: Hmisc > Loading required package: survival > Loading required package: stats > Loading required package: graphics > Loading required package: splines > Attaching package: 'Hmisc'

R 4.2.1 OS X Colleagues I am using XOJO (formerly known as RealBasic) to create a GUI -- R code generates the text that appears in the GUI. Recently, VT-100 terminal control escape sequences appeared in the text, e.g.,: [?25h TEXT [?25h[?25h TEXT It is not clear to me if the problem is generated by R or by XOJO. And I did not track whether this began following installation of a

Luke Thanks ? I revised the code to: ERRORMESSAGE <- try(source(USERSCRIPTFILE, local=T), silent=T) print(ERRORMESSAGE) now returns: $value [1] 0 $visible [1] FALSE Not clear what to make of that.

R 3.4.3 OS X Colleagues I have a 20K line script in which I encounter an unexpected problem. If the script detects presence of a particular file USERCODE.txt, it executes: source(?USERCODE.txt?) If that file is not present, the script executes without a problem. There might be syntax errors in USERCODE.txt; therefore, the code above is embedded in a try command:

Only the default error handler puts the error message in a buffer where it can be retrieved with geterrmessage. try() replaces the default error handler. Either look at the value returned by try() or use tryCatch with conditionMessage.

R 3.1.0 OS X Colleagues, I recently updated to 3.1.0 and I have encountered Warning messages: ... Name partially matched in data frame when I do something like: DATAFRAME$colname where colname is actually something longer than that (but unambiguous). I have much appreciated the partial matching capabilities because it fits with my workflow. I often receive updated data months after the

Colleagues, (R 2.10 on all platforms) I have a lengthy script (18000 lines) that runs within a graphical interface. The script consists of 100's of function followed by a single command that calls these functions (execution depends on a number of environment variables passed to the script). As a result, nothing is executed until the final line of code is read. It takes 15-20

Colleagues, I have encountered a problem in version 2.9 of R, running in both Vista and OS X. My code is quite lengthy but the critical line is: if (file.exists(FILENAME)) readLines(FILENAME)) This triggers the error: Error in file(con, "r") : cannot open the connection Calls: readLines -> file Execution halted The file that it is reading is being created on the fly, then

Colleagues R 2.10.1 on a Mac I read in textfiles using readLines, then I process those files, then I use R to execute another program. Occasionally those files contain characters other than letter / numbers / routine punctuation marks. For example, a bullet (option-8 on a Mac) triggers the problem. Although R can read and process those characters, the other program cannot so I would like to

Colleagues R: 2.12.2 OS X I have a set of text objects in the form (I am showing 3 of what is more likely to be 20 or so): OBJECTS <- c("abcSOMETHINGCOMMONegf", "xSOMETHINGCOMMONyz", "SOMETHINGCOMMONnme") As you can see, all contain "SOMETHINGCOMMON" and the position varies. But, I don't know what that "SOMETHINGCOMMON" is. Is there an

Colleagues, What is the easiest means to embed a: ? (registered) or ? (trademark) sign in text in a graphic. I would like to use mtext and avoid plotmath, if possible. Ideally, the sign should be superscripted but I can easily sacrifice that. Optimally, I need a solution that works in both OS X and Windows (? XP) and with R versions ? 2.11 Thanks in advance.

R 2.12.2 Windows 7 Colleagues, I just took advantage of the function: readWindowsShortcut in R.utils. It accomplished my goals and I was interested in learning its inner workings. So, I typed the function at the command line (without arguments or parentheses). R returned: function (...) UseMethod("readWindowsShortcut") <environment: namespace:R.utils> providing no

Colleagues, I am trying to understand how R (2.12.1) obtains the PATH environment variable in Windows (7 or Vista). Startup {base} directs one to: "R_ENVIRON" -- which equals "" in my systems R_HOME/etc/Renviron.site -- which does not exist Next, it directs to: R_HOME/etc/Rprofile.site -- which also does not exist (the expected behavior in a "factory-fresh"

R 2.15.1 OS X.7.4 Colleagues, I have a large dataset (27773536 records, the file is several GB) that contains a column of date / time entries in the format: "2/1/2011 13:25:01" I need to convert these to numeric values (ideally in seconds; the origin [e.g., 1970-01-01] is not important). I am using: as.numeric(strptime(DATA$DATADTM, "%m/%d/%Y %H:%M:%S")) It takes 21

Colleagues, Several days ago, I wrote to the list about a lengthy delay in startup of a a script. I will start with a brief summary of that email. I have a 10,000 line script of which the final 3000 lines constitute a function. The script contains time-markers (cat(date()) to that I can determine how fast it was read. When I invoke the script from the OS ("R --slave <

Colleagues OS 10.5 R: 2.10.1 I have a simple x-y plot for which I would like to shade the lower (or upper) part of the interior region (i.e., the area bounded by the axes). If the delineation between top and bottom were linear, it would be use to use the polygon function. However, the delineation is a curve (which I can describe by an equation). In theory, I could divide the x-axis into a

Colleagues, [R 2.11; OS X] I am processing a file on the fly that contains the following text: XXX?? [email clients may display this differently -- the string is three X's followed by two instances of the letter a with an acute accent] I read the file with: X <- readLines(FILENAME) In this instance, the text of interest is on line 213. When I examine line 213, it reads: XXX\xe1\xe1

Colleagues, I am trying to create a PDF document in which I use margin text with two different fonts. The resulting text might be: XXXXXyZZZ where X and Z are one font and Y is the other. My plan was to do this in the following manner: mtext("XXXXX ZZZ", cex=2, adj=0.5, family=SOMEFONT) mtext("Y", cex=2, adj=??, family=DIFFERENTFONT) My question regards how to calculate

Mark Thanks for pointing this out. I did a default installation of R. Does this mean that I need to reinstall from the command line?

Colleagues, I have a script that contains ~ 10,000 lines of code. Most of it is written as small functions. However, for various reasons, the final function is ~1500 lines of code. I realize that this may not be optimal but the code evolved that way and breaking it into smaller pieces is complicated because of the passing of arguments. I have "cat(date())" statements at
