I have a statistical question. The data sets I am working with are right-skewed so I have been plotting the log transformations of my data. I am using a Grubbs Test to detect outliers in the data, but I get different outcomes depending on whether I run the test on the original data or the log(data). Here is one of the problematic sets: fgf2p50=c(1.563,2.161,2.529,2.726,2.442,5.047)

Hi, I don't know what I am doing wrong to the toupper does not seem working in sub + regex. The following returns 's' not the upper class 'S' as I expect: sub("q_([a-z])[a-zA-Z]*",toupper('\\1'),"q_sviRaw") Can someone tell me where I did wrong? Thanks, Richard [[alternative HTML version deleted]]

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 <-

Hi, So far with the latest changes the projects I am trying to port works fine, except for a mismatch on what is considered the ansi behaviour of islower() in ctype.h: ----- i = 220 islower (i) = 0, ISLOWER (i) = 0 toupper (i) = 220, TOUPPER (i) = 220 i = 221 islower (i) = 0, ISLOWER (i) = 0 toupper (i) = 221, TOUPPER (i) = 221 i = 222 islower (i) = 0, ISLOWER (i) = 0 toupper (i) = 222, TOUPPER

Hi All, I am trying to match two character arrays (email lists) using either pmatch(), match() or charmatch() functions. However the function is "missing" some matches due to differences in the cases of some letters between the two arrays. Is there any way to disable case sensitivity or is there an entirely better way to match two character arrays that have identical entries but written

You left out all the most important bits of information. What is yo? Are you trying to assign a data frame to a single column in another data frame? Printing head(samples) tells us nothing about what data types you have, especially if the things that look like text are really factors that were created when you used one of the read.*() functions. Use str(samples) to see what you are dealing with.

Dear all, Given the following vector: > (z <- c('R project', 'hello world', 'something Else')) [1] "R project" "hello world" "something Else" I know how to obtain all capitals or all lower case letters: > tolower(z) [1] "r project" "hello world" "something else" > toupper(z) [1] "R

Hi Peter, Thanks for contributing such a great answer. Can you please provide a pointer to the documentation where it explains why dd$B <- s and dd["B"] <- s have such different behavior? (I am perfectly happy if you write the explanation but if it saves you time to point to some reference that works fine for me.) Regards, Eric On Wed, Oct 25, 2017 at 2:27 PM, Peter Dalgaard

Our legacy PBX will not accept the callerID name in anything but capital letters. (Harris 20-20) When I send a call to the legacy PBX from asterisk I would like to have asterisk convert the callerID name to uppercase letters. Is there a way to do this? Thanks for any input. -Sean

Hi all, I'm using R to find duplicates in a set of 6 files containing Part Number information. Before applying the intersect method to identify the duplicates I need to normalize the P/Ns. Converting the P/N to uppercase if alphanumerical and applying an 18 char long zero padding if numerical. When I apply the pn_formatting function (see code below) to "Part Number" column of the

Hi Jakob and David, The for-loop inside multiclass definition does not have to add extra abstraction layer. As in the pseudo codes that David wrote earlier (see below), it only condenses the repetitive 'def' statements inside the multiclass definition into a more compact and less copy-paste style form, instead of encapsulating them somewhere outside the multiclass definition. I believe

Dear Any, Is there a fonction in R to change a string to uppercase ? Thanks for all your help

I am trying to write a function to change the case of all of the text in a data frame to lower case. I do not have foreknowledge of the data frame names or the data types of each column. It seems that if one references the data frame by index, then it returns class "data.frame" but if it is referenced by name, it returns class "factor" or whatever the column actually is:

Hello, I'm working on a Cox Proportional Hazards model for a cancer data set that has missing values for the categorical variable "Grade" in less than 10% of the observations. I'm not a statistician, but based on my readings of Frank Harrell's book it seems to be a candidate for using multiple imputation technique(s). I understand the concepts behind imputation, but using
