How can I delete both rows and columns that do not meet a particular cut off value. Example: > d <- rbind(c(0, 1, 6, 4), + c(2, 5, 7, 5), + c(3, 6, 1, 6), + c(4, 4, 4, 4)) > f <- as.matrix(d) > f [,1] [,2] [,3] [,4] [1,] 0 1 6 4 [2,] 2 5 7 5 [3,] 3 6 1 6 [4,] 4 4 4 4 I would like to delete all

Hello, Everyone, I am a student an a new learner of R and I am trying to do my homework in R. I have 10 files need to be read and process seperately. I really want to write the codes into something like "macro" to save the lines instead of repeating 10 times of similar work. The following is part of my codes and I only extracted three lines for each repeating section. data.1 <-

Hi, I'm try to collect a list of methods/packages available in R for doing in-string variable/symbol substitution, e.g. someFcn("pi=${pi}"), anotherFcn("pi=@pi@") and so on becomes "pi=3.141593". I am aware of the following: ** gsubfn() in the 'gsubfn' package, e.g. > gsubfn( , , "pi = $pi, 2pi = `2*pi`") [1] "pi = 3.14159265358979,

the content of th character vector (of length 1) is as follows: a <- "something2 ....pat1 name1 pat2 something2....pat1 name2 pat2....pat1 name3 pat2 " I would like to extract the character bewteen pat1 and pat2. That's to say, I would like to get a vecter of c("name1", "name2","name3"). What I did is use strsplit() twise. But I wonder if there

Dear R-users! I am using R 1.7.0, under Windows XP. Having some hospital discharge data (admission date and discharge date for each patient), I want to get the number of patients in the hospital on a given date. My data look like (simple example): > x <- data.frame(patid=c("pat1", "pat2"), adm.date = c("15.03.2002", "16.03.2002"),

Dear R-helper, Please suggest some methods for my question below. We measured the amount of protein A in patient blood in pre-treatment and post-treatment condition from 32 patients. -------------------------------------------- Pre-treatment Post-treatment Pat1 25 28 Pat2 19 15 Pat3 94

Dear list, I have the following text to parse (originating from readLines as some lines have unequal size), st = c("START text1 1 text2 2.3", "whatever intermediate text", "START text1 23.4 text2 3.1415") from which I'd like to extract the lines starting with "START", and group the subsequent fields in a data.frame in this format: text1 text2

Hello all, Can any of you R gurus help me out? I?m not all that great at stats to begin with, and I?m also learning the R ropes (former SAS user). Here?s what I need help with? I have a nested sample design and ran a nested anova, but I don?t know how to interpret the results habitat (four different types) is nested in site (three types), and site is nested in gear (two types)

Hi, I applied a linear mixed effect model in my data using the nlme package. lme2<-lme(distance~temperature*condition, random=~+1|trial, data) and then anova. I want to ask if it is posible to get the least squares means for the interaction effect and the corresponding 95%ci. And then plot this values. Thank you Panagiotis -- View this message in context:

Hi Everyone, I have a question regarding the construction of 3D graphs in 'R', BUT these graphs also need to illustrate movement (with time) of the prostate gland (using radiological techniques). I am not sure how to do this in 'R' although I'm sure there is some way of doing it. Below, I have copied and pasted some of the data with which I'm working on. The data

Hi, Here's the deal. When someone leaves me a voicemail message I want Asterisk to call me on my cellphone by dialing my cellphone number and tell me I have a message. Is this possible? Can anyone cite examples? Most commercial voicemail systems produced in the last 10 years can do this. Any help would be much appreciated.

Full_Name: Martin O'Gorman Version: OS: Submission from: (NULL) (84.176.63.149) I have been looking at the PPC package and have a question. As the input data is comma separated, shouldn?t the command to read in the raw (no batch) mass spec data indicate that sep=?,? (marked below) ? Otherwise, the data read in is the pair of values (m/z,intensity). It is not obvious why that should be.

Hi, When the Dovecot 1.0.rc19 IMAP server encounters X-UID headers with gaps in them, it hangs indefinitely. I've attached a sample mailbox (in mbox format) which repeatably exhibits this behavior. The mbox contains only three messages with the following X-UIDs in order: 774, 785, 787. If I remove the X-UID headers from each message, Dovecot handles the mailbox without any problems. UW-IMAP

The subject line says it all really. I'm running Samba 2.0.4.b on FreeBSD, sharing a tree as I normally do (we use samba on about a dozen machines so I'm reasonably familiar with it).

Besides email notification, is there another way to get asterisk notify the user that they have a message? Example: Some analog phones have a blinking light that lets the user know that they have a voicemail message. Is asterisk capable of doing this?
