Create a function with multiple object as an output
I've seen some questions regarding the output of multiple objects from a function, however the suggestions all end up suggesting the use of return(list(result1=result1, result2=result2 , result3=result3)). How can I return multiple objects that are 2 big to be added to a list? -- View this message in context:

Speeding up a bootstrap routine
I have written the R code below to perform White's Data Mining Reality Check (DMRC) but as it stands at the moment it is painfully slow. It is written as a function as I call it many times from a script file with different data input, and the output is sunk() to a text file. Could anyone suggest improvements to the code to increase its speed? boot_white_test <- function(data) {

R FAQ 2.6, 7.21
Hello R-devel, I would like to suggest a couple of updates for the R FAQ. https://CRAN.R-project.org/bin/linux/suse is currently empty and the directory has mtime from 2012, so it probably doesn't help to reference it in FAQ 2.6. There seems to be increased interest in using variables as variable names [1,2], so it might be useful to expand 7.21 a little. Can an R FAQ entry link to R-intro

xtabs
Hi, In Splus if I call the function crosstabs() the output is a contigency table; in each cell of the table is printed: N, N/RowTotal, N/ColTotal, N/Total. N is the number of observations in each cell. The same call to xtabs() in R will produce the contigency table but the only entry in each cell is N. How can I get the same relative frequencies that crosstabs() gives? Thanks, mike --

questions about optim
Hi, I am trying to do parameter estimation with optim, but I can't get it to work quite right-- I have an equation X = Y where X is a gaussian, Y is a multinomial distribution, and I am trying to estimate the probabilities of Y( the mean and sd of X are known ), Theta1, Theta2, Theta3, and Theta4; I do not know how I can specify the constraint that Theta1 + Theta2 + Theta3 + Theta4 = 1 in

Elegant Code
Hi, Can anyone help to write a more elegant version of my code? I am sure this can be put into a loop but I am having trouble creating the objects b1,b2,b3,...,etc. b1 <- rigamma(50,1,1) theta1 <- rgamma(50,0.5,(1/b1)) sim1 <- rpois(50,theta1) b2 <- rigamma(50,1,1) theta2 <- rgamma(50,0.5,(1/b2)) sim2 <- rpois(50,theta2) b3 <- rigamma(50,1,1) theta3 <-

Hi Dennis, How about: # define the two values to search for x<-2 y<-3 # create your search string and replacement string repstring<-paste(x,y,sep=",") newstring<-paste(x,y,sep=".") # this is the string that you want to change thetastring<-"SIGMA(2,3)" sub(repstring,newstring,thetastring) [1] "SIGMA(2.3)" Use gsub if you want to change

Help with regular expressions
You can either use positive lookahead/lookbehind - but support for that is a bit flaky. Or write a proper regex, and use backreferences to keep what you need. R > x <- "abc 1,1 ,1 1, x,y 2,3 " R > gsub("(\\d),(\\d)", "\\1.\\2", x, perl = TRUE) [1] "abc 1.1 ,1 1, x,y 2.3 " B. > On Feb 12, 2018, at 9:34 PM, Jim Lemon <drjimlemon at

4-parameter logistic model
Dear R users I'm a new user of R and I have a basic question about the 4-parameter logistic model. According to the information from Pinheiro & Bates the model is: y(x)=theta1+(theta2-theta1)/(1+exp((theta3-x)/theta4)) == y(x)=A+(B-A)/(1+exp((xmid-input)/scal)) from the graph in page 518 of the book of the same authors (mixed models in S) theta 1 corresponds to the horizontal asymptote

[PATCH v5 2/7] tests/c-api: Convert the C API tests to use the test harness.
This involves some significant changes to this test framework. In particular: - Instead of just specifying $srcdir at the start of a FileIn path, you can now specify arbitrary environment variables. This is necessary to allow the tests to run from a tmpdir. - Use COPYING instead of COPYING.LIB, and copy that file into the test suite directory. - Require the static binaries

Adjusting for autocorrelation in a panel model
I am working with panel data. I am using the plm package to do this. I would like to do be able to adjust for autocorrelation, as one does with glm models and correlation structures (eg corr=corARMA(q=4)) . In particular, I want to employ MA(4) error structure. Is there a way of doing this with the plm package? (Note: I do not really want to use the pggls function for various

[PATCH 00/16] Small bits of non-Linux porting
Hi, from time to time, there have been requests (or attempts, like the mingw port posted on the list some months ago) to make libguestfs work on OSes different than Linux. Of course this would imply using a fixed appliance, since it is currently heavily dependent on Linux. The attached series provides some easy changes in this direction, resolving some of the easy issues found in porting to
