R 4.0.2 OS X Colleagues I have the unfortunate need to create a large number of tables (destined for a Word document). I need to color cells depending on the contents, e.g., blue if the value is < 0.5, red if the value is > 1.5. If the output went initially to Excel, that would work; outputting directly to Word would be even better. I expect that several packages can accomplish this. I

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 2.10.1 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 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)?

OS X R 4.3.1 Colleagues I often create multipage PDFs [pdf()] in which the text "Page X" appears in the margin. These PDFs are created automatically using a massive R script. One of my clients requested that I change this to: Page X of XX where XX is the total number of pages. I don't know the number of expected pages so I can't think of any clever way to do this. I

Colleagues, I have created a list in the following manner: TEST <- list(c("A1", "A2"), c("B1", "B2"), c("C1", "C2")) I now want to delete one element from the list, e.g., the third. The command TEST[[3]] yields (as expected): [1] "C1" "C2" The command TEST[[-3]] yields: Error:

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 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 =

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

R 3.4.2 OS X Colleagues I would appreciate some help with regular expressions. I have string that looks like: " ITERATION ,THETA1 ,THETA2 ,THETA3 ,THETA4 ,THETA5 ,THETA6 ,THETA7 ,SIGMA(1,1) ,SIGMA(2,1) ,SIGMA(2,2)? In the entries that

Colleagues, I have some text: TEXT <- c("a", "bb;ccc", "dddd;eeeee;ffffff") I want to retrieve the portion of each element before the first semicolon. I can split each element using strsplit: SPLIT <- strsplit(TEXT, ";") This yields: > SPLIT [[1]] [1] "a" [[2]] [1] "bb" "ccc" [[3]] [1] "dddd"

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

R 4.2.3 OS X Colleagues, I am printing a large number of tables using the print command. A simple example is: print(data.frame(COL1=1:5, COL2=10:6)) The result in this case is: COL1 COL2 1 1 10 2 2 9 3 3 8 4 4 7 5 5 6 I would like to print the table WITHOUT the row numbers: COL1 COL2 1 10 2 9 3 8 4 7 5 6 Is there any simple

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 <-

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 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 SASxport/R folder, I found all the functions that are part of the package. I became interested in whether I could

Colleagues: I have encountered the following situation: SERIES OF COMMANDS source("File1") MORE COMMANDS source("File2") Optimally, I would like File1 and File2 to be merged into a single file (FileMerged). However, if I wrote the following: SERIES OF COMMANDS source("FileMerged") MORE COMMANDS I encounter an error: the File2 portion of FileMerged

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 After reading in some clinical data, I discovered that the subject ID column contains entries only for the first record for each individual; subsequent rows are recorded as NA. For example: > 1 > NA > NA > NA > NA > 2 > NA > NA > NA > NA > 3 > NA > NA > ... I can think of various approaches to replace the NA values with appropriate
