Re: [R] Q-Q Plot for loglogistic, lognormal and 2 parameter exponential distributions

A basic approach is x <- rchisq(1000, 4) qqplot(qchisq(ppoints(x), 4), x) abline(0,1) Substitute whatever distribution and parameters that might apply. Notice that if you don't have a location-scale family of distributions, you need to compare to the identity line, not just look for linearity.

[R] How to sum some columns based on their names

I want to sum columns based on their names. As an exampel how could I sum columns which contain 6574, 7584 and 85 as column names? In addition, how could I sum those which contain 6574, 7584 and 85 in ther names and have a prefix "f". My data contains several variables with I want to sum columns

Re: [R] How to sum some columns based on their names

You can use grep with some basic regex, index your dataframe, and colSums colSums(df[,grep("*6574*|*7584*|*85*", colnames(df))]) colSums(df[,grep("f6574*|f7584*|f85*", colnames(df))]) Regards, Dr. Charles Determan On Mon, Oct 13, 2014 at 7:57 AM, Kuma Raj wrote: > I want to sum columns based

Re: [R] How to sum some columns based on their names

Learn regular expressions.. there are many websites and books that describe how they work. R has a number of functions that use them... ?regexp ?grep For example... grep("^[^0-9]*(6574|85|7584)[^0-9]*$",names(dta)) where dta is your data frame. You can read that regular expression as zero or

Re: [R] How to sum some columns based on their names

Your regular expressions are invalid, Charles. You seem to be thinking of file name globbing as at the command line. --- Jeff NewmillerThe . . Go Live... DCN:Basics: ##.#.

Re: [R] seqinr ?: Splitting a factor name into several columns. Dealing with metabarcoding data.

I'm not sure I understood your problem, maybe like this: # split identifiers into columns df1 <- data.frame(cbind(X = 1:10, Y = rnorm(10)), Z.identifierA.B1298712 = factor(rep(LETTERS[1:2], each = 5))) id <- names(df1)[3] x <- do.call(rbind, str_split(id, "\\.")) y <- sapply(x,

Re: [R] Loading a rda file for predicton

see help(load) and pay particular attention to what the function returns: the names of the loaded objects, not the object(s) themselves. You have to use predict(fit,Testsamp,type="response") since the load() created a variable 'fit' (same name as the one saved). HTH Peter On Mon, Oct 13, 20
