Hi, I have a dataframe Wash2005, which has daily weather data. I am doing a regression by month as follows: # FM10 Regression by Month # Plot 12 Month of OFM10, FFM10 for(i in 1:12) { Temp <- subset (Wash2005, MM == i) assign( paste('Wash2005FM10', strtrim(month.name[i],3), sep=""),lm(Temp$FM10.1 ~ Temp$FM10)) } Wash2005FM10Jan, Wash2005FM10Feb, etc holds the regression results for each month. Now, I want to sum up the residuals of all the 12 regression. How can I do that in a loop? For (i in 1:12){ Temp <- paste('sum(Wa...

hi everyone . Here I have a text where there are some integer and string variables.But I can not read them by readLines and scan the text is : weight ;30;130 food:2;1;12 color:white;black the first column is the names of the variables and others are the value of them. the column in different line are different. Can anyone help me ? -- TANG Jie Email: totangjie@gmail.com Tel: 0086-2154896104

...anguage I've ever seen has a string function that trims blanks off strings (off the front or back or both). Ideally, it would process whole data frames/matrices etc but I don't even see one that processes a single string. But I've searched and I don't even see that. There's a strtrim function but it does something completely different. -- View this message in context: http://www.nabble.com/Function-for-trim-blanks-from-a-string%28s%29--tf4226133.html#a12022374 Sent from the R help mailing list archive at Nabble.com.

fansi provides counterparts to the base string manipulation functions substr, strwrap, strtrim, strsplit, and n(z)char that account for ANSI CSI SGR control sequences.? ANSI CSI SGR control sequences [1] can be used to format text in terminals that support them. For example the control sequence "\033[31m" causes text that follows to render in red, and the control sequence "\0...

I have a dataframe with almost a million rows which has one column with strings. That column has several entries with the words "South", "North", "East" and "West" which I would like to replace with S, N, E, and W, respectively. Obviously, I can use gsub multiple times df $col2 <- gsub("West", "W", df$col2) which will require

...rinsics and I know what they do." For R, I found it an intimidating task to flip through the 400+ pages core and retain a clear mind at the end. Below is a random sample of string related functions in the core package: agrep basename charmatch chartr gregexpr grep gsub regex regexpr strsplit strtrim strwrap sub In my opinion, anything that uses regular expressions belongs somewhere else. Even 'utils' seems to be a better place for random items than the 'core'. 2. Benefits of a smaller core a) A smaller core will be more carefully studied and better appreciated. If the R cor...

Dear R wizes, I have a data.frame of species abundances with column names consisting of 4 letter codes then an underscore and a number like this: abco_1, abco_2, abco_3, psm_1, psme_2, psme_3, etc. I would like to get an identifier for all the abco, and psme and other species etc. I used spec.fact<-substring(names(spec.count),1,4) To make a vector of the first 4 letters of

Hello, Is there a way to convert a character to a number with out getting a warning? I have a vector that has both numbers and letters in it and I need to convert it to only numbers. At the moment I'm using as.numeric but it is generating a warning when it converts a letter. Is there another function out there that will do what I need or is there a way to turn off the warnings as I
