Hi Mario, It is at the limit of my skills so I'm not sure this will be a real solution. But it might help you anyway (and there will be more competent people anyway). What does not make sense to me is why you set the names of your files and then use them to list them with list.files() What

[R] Importing data by targeting in filenames inside a nested list

Hello everyone, So, rookie me is trying to write a smart code, so here's what I'm doing: I have a list of a couple of hundrend files, some of which refer to different experiments. The naming of the file refers to the experiment and the serial number to the topological reference on my sample.

The first and second argument of forest() (or more precisely, forest.default()) are for the estimates and the corresponding sampling variances, respectively. So, if you do forest(rr, se, ...), then the function will interpret the standard errors as if they are variances. So, you should do

[R] column means dropping column minimum

Suppose I have something like the following dataframe: samp1 <- c(60,50,20,90) samp2 <- c(60,60,90,58) samp3 <- c(25,65,65,90) test <- data.frame(samp1,samp2,samp3) I want to calculate column means. Easy enough, if I want to use all the data within each column: print(colMeans(test),na.rm =

Re: [R] column means dropping column minimum

There is a bug in your code: it is not > for (i in 1:ncol(test)) { test2[which.min(test[,i]),i]==NA} but for (i in 1:ncos(test)) { test2[which.min(test[, i]), i] <- NA } Otherwise, a solution would be to create your own function to compute the mean of a vector without the smallest value:

Re: [R] column means dropping column minimum

First, your code has flaws in the assignment of NA and in passing na.rm=TRUE to colMeans(). It should be: test2 <- test for (i in 1:ncol(test)) { test2[which.min(test[,i]),i]=NA} print(test2) samp1 samp2 samp3 16060NA 2506065 3NA9065 490NA90

Re: [R] column means dropping column minimum

The which.min() only gets the first minimum value. If two or more values are tied for the minimum, it will delete only the first one. This would get them all: > apply(test, 2, function(x) mean(x[-which(x == min(x))])) samp1samp2samp3 66.7 70.0 73.3

Re: [R] Why mean is not working in by?

Sarah: Note that (as I read them) aggregate() and by() work differently on data frames. aggregate() computes FUN column by column while by() feeds the whole (subset) data frame to FUN. If I am wrong about this, I would greatly appreciate being corrected. Cheers, Bert Bert Gunter "Data is

Re: [R] Why mean is not working in by?

by() calls FUN with a data.frame as the argument. summary(), sum(), etc. have methods that work on data.frames but sd() and mean() do not. aggregate() calls its FUN with each column of a data.frame as the argument. Bill Dunlap TIBCO Software wdunlap tibco.com On Tue, Dec 8, 2015 at 3:08 PM,

Are you sure this is the right way to go for your use case? Even if you got a quick solution to display an 1e4 x 100 table in TkTable, what is the purpose of it? Will the user browse the whole dataset that way? Even if the answer is yes, you would probably need to implement sorting and

Re: [R] Why mean is not working in by?

Because you are using by() incorrectly. "A data frame is split by row into **data frames** subsetted by the values of one or more factors, and function FUN is applied to each subset in turn." So your FUN is applied to a subset of the data frame (which is also a list). Note that sum, min, and
