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

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 using R (2.9.2, all platforms) to search for a complicated text string using regular expressions. I would appreciate any help you can provide. The string consists of the following elements: SOMEWORDWITHNOSPACES any number of spaces and/or tabs ( any number of spaces and/or tabs integer any number of spaces and/or tabs ) Examples include: WORD ( 123 ) WORD(1 )

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

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, 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.

Colleagues Assume that I have a vector containing some text strings, some of which contain a particular character. I could like to apply "toupper" to the text before the character. For example (in this case, "|" is the particular character): ORIGINAL: TEXT <- c("aaaa", "bbb|cc", "|ddd") AFTER APPLICATION OF toupper: TEXT <-

Will this need to be done many times? If not, it might be just as easy to apply conditional formatting to cells after they're already in Excel.

R 4.2.2 OS X Colleagues A file that I have read includes strings like this: "EVENT ? 30 sec" When I include the string in a graphic using: mtext(STRING, ?) it appears as: "EVENT ... 30 sec" Is there a simple work-around (short of reformatting all the strings, then using plotmath)?

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.

Colleagues I am learning lattice graphics (R 2.12.2; OS X). Several days ago, I inquired about adding margin text to lattice graphics. Jim Price offered a useful reply, suggesting that I add: page = function(page) grid.text('words', x = 0.5, y = 0.01) to my call to the function. The entire function that he suggested was; xyplot(1 ~ 1, par.settings = list(layout.heights =

Colleagues, Hopefully a simple problem: I want to delete a column with a known name from a dataframe. I could write: FRAME <- FRAME[, names(FRAME) != NAMETODELETE] or FRAME <- FRAME[, !names(FRAME) %in% c(NAME1, NAME2, ETC)] Is there some simpler means to accomplish this?

Colleagues, I want to create the following array: "A1", "A2", "A3", "B1", "B2", "B3", "C1", "C2", "C3" I recall that there is a trick using "c" or "paste" permitting me to form all combinations of c("A", "B", "C") and 1:3. But, I can't recall the

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

Hello list, I'm trying to figure out how exactly the specification of nested random effects works in the lmer function of lme4. To give a concrete example, consider the rat-liver dataset from the R book (rats.txt from: http://www.bio.ic.ac.uk/research/mjcraw/therbook/data/ ). Crawley suggests to analyze this data in the following way: library(lme4) attach(rats) Treatment <-

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"

Hello, I used the function cor to calculate the pearson correlation coefficient between variables. However, the resulting values do not correspond to the outcome of my excel-calculations, for which I used the formula Cor(x,y)=Cov(x,y)/(SD(x)*SD(y)) So my question is: How does the function "cor" compute the pearson correlation coefficient? Thank you in advance, Ake Nauta

I am using: as.numeric(strptime(DATA$DATADTM, "%m/%d/%Y %H:%M:%S")) It takes 21
