Identifying special characters in a text file
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

Probing a function
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

Finding the common portion of strings
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

Registered / trademark signs
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.

Applying "toupper" to only portions of text strings
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 <-

Adding margin text to lattice graphics
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 =

Environment variable PATH in Windows
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"

Printing special characters
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)?

Speeding up time conversion
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

(no subject)
Hi all, I am looking for a clever way to create the following graph using R: I got information on the shares of some subgroups over time (summing up to 1 in each year). The graph I want to create should display the development of the individual shares over time by shading rectangulars for each share in a different color. Is there a clever of doing this? Thanks for your help Stefan

Use of apply rather than a loop
Colleagues, R 2.9.0 on all platforms I have a dataset that contains three columns of interest: ID's, serial elapsed times, and a marker. Representative data: Subject Time Marker 1 100.5 0 1 101 0 1 102 1 1 103 0 1 105 0 For each subject, I would like to find the time associated with MARKER == 1, then replace Time with Time - (Time[Marker == 1]) The result for this

grep triggering error on unicode character
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

Deleting a column in a dataframe by name
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?

Package recommendations for outputting table with cell formatting

Shading area under density curves
Hello, I have a question regarding shading regions under curves to display 95% confidence intervals. I generated bootstrap results for the slope and intercept of a simple linear regression model using the following code (borrowed from JJ Faraway 2005): > attach(allposs.nine.d) > x<-model.matrix(~log(d.dist,10))[,-1] > bcoef<-matrix(0,1000,2) > for(i in 1:1000){ +
