Hi, I'm newish to R, a recent convert from Matlab... So far I'm impressed, and determined to solve the following problem, which seems like it should be easy: I have a long (millions of points) data series recorded with a datalogger that produced a timestamp in 4 columns: Year, Day of Year, Time in (H)HMM and Seconds. I would like to have R interpret these columns as a time object and have

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

I feel like an idiot posting this because every language 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

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

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

Hello, everybody, There is the first time for me to post a question, because I really cannot find answer from books, websites or my colleagues. Thank you in advance for your help! I am running likelihood ratio test to find if the simpler model is not significant from more complicated model. However, when I run LRT to compare them, the test did not return F value and p-value for me. What's the

I am a little bit confusing about the following help message on how to fit a GAM model with interaction between factor and smooth terms from http://rss.acs.unt.edu/Rdoc/library/mgcv/html/gam.models.html: ?Sometimes models of the form: E(y)=b0+f(x)z need to be estimated (where f is a smooth function, as usual.) The appropriate formula is: y~z+s(x,by=z) - the by argument ensures that the smooth

Identified as root cause of a bug in data.table: https://github.com/Rdatatable/data.table/issues/3267 On my machine, strtoi("", base = 2L) produces NA_integer_ (which seems consistent with ?strtoi: "Values which cannot be interpreted as integers or would overflow are returned as NA_integer_"). But on all the other machines I've seen, 0L is returned. This seems to be

Thanks very much for your answer. I?m trying the function ?strtoi? but it fails to convert character to numeric after the command "set[index] <- strtoi(set[index])". > strtoi(set[index]) ## This works: all values are numeric !!! [1] 1 2 3 4 2 8 9 7 > set[index] <- strtoi(set[index]) > print(set[10,1]) ## Problem: must be numeric !!!! [1] "1" Thanks

Thanks Martin.

Hi, I've used the following patch First because re-defining strtoi is a problem, and it's named Strtoi elsewhere. Second because that is the sole use of strtoi that isn't Strtoi. Third, use = instead of ==, which is bash-specific. Additionally I must note there are a number of tests in configure.ac which do not append x to the beginning of the string. I have been told that it may
