Re: [R] Find the max entry in column 2 - that satisfies a condition given a fixed entry in column 1

Hello, Thinking again, if all you want is vector b the following function fun2 will do it without having to create plain. Less memory and (much) faster. fun2 <- function(X, val){ u <- sort(unique(X)) n <- length(u) b <- numeric(n^2) b[n*(n - 1) + match(val, u)] <- u[n] b }

[R] Problem with random numbers/seed

Dear all, I did all this work with older R (R-3.5.3.patched and older) but now with R3.6 I cannot replicate the results. Below I sample 60 observations from 1:500 using the sample command with a random seed of 123. I get different results. Advice appreciated. Steven Yen > # Run under R-3.6.0 >

Re: [R] Problem with random numbers/seed

What does not work? For me it works under R-3.6.0: x<-1:500 set.seed(12345671) j<-sample(1:length(x),size=60); y<-x[j] summary(j) RNGversion("3.5.3") set.seed(12345671) j<-sample(1:length(x),size=60); y<-x[j] summary(j) Now I get the results you got udner the old R. Best, Uwe

You should ask someone at RStudio about this, but *.Rproj files are not something R itself knows about. load() reads files made by save(), which usually have the extension ".Rdata" or ".rda". Bill Dunlap TIBCO Software wdunlap tibco.com On Fri, Jun 21, 2019 at 1:43 PM Spencer Brackett <

Reading the file with row.names=1 meant to make rownames out of the first column in the text file. Duplicate row names are not accepted. To diagnose, read it with row.names=NULL and see what is in the first column (e.g., use the table function on it). Bill Dunlap TIBCO Software wdunlap
