...te model. I cannot pass a matrix to predict - when I pass a data frame I get the fitted valuie which leads me to think that R doesnt see the data.frame I pass to predict Thanks in advance, Paolo # REPRODUCIBLE CODE x <- matrix(rnorm(30), ncol =2) y <- 1 + 3*x[, 1] + 2*x[, 1] + rnorm(15) new_x <- matrix(rnorm(2), ncol =2) new_x.d <- data.frame(new_x) # fitted values predict(lm(y ~ x)) # same as fitted values predict(lm(y ~ x), new_x.d) # error predict(lm(y ~ x), new_x) [[alternative HTML version deleted]]

...t to extend an existing loess fit to a new data set is producing error. I was trying the following: dat = read.csv(choose.files()) x = dat[,2]; y = dat[,1] x.sort = sort(x) y.loess = loess(y~x, span=0.75) # For testing the above fit with a new dataset: test = read.csv(choose.files()) # test data new_x = test [,1]; new_y = test[,2] new_x.sort = sort(new_x) predicted <- predict(y.loess, newdata=new_x.sort) Am I doing any mistake ? Please correct me. I could see that though the rest of the values of "predicted" looks alright, however the first output of it is an NA !! Many thanks,...

...39;splines' package, it is possible to fit a model of some property with depth based on the bs() function: #natual, B-Splines library(splines) #fit a b-spline model: fm <- lm(y ~ bs(x, df=5) ) I am able to predict a soil property with depth, at unsampled locations with this model with: new_x <- seq(range(x)[1], range(x)[2], len = 200) #predict attribute at unsampled depths: new_y <- predict(fm, data.frame(x=new_x) ) #plot the predicted attribute at the unsampled depths lines(new_x, new_y, col='red') This tends to work fairly well (see attached), but I am wondering if...

...'s checks (it passes the spline one failed by the 32-bit version which I asked about yesterday). Well, it fails the same procedure twice, but not all the time. The error is found in a call to the `factanal` procedure, specifically the call to `optim` therein, and it returns an error code "NEW_X", which I have never seen before. It fails this call in the checks for both stats.R and datasets.R, but does not fail them all, and for those it works, it returns the proper answers. The first call that fails is in statsEx.Rout fa <- factanal( ~., 2, data = swiss) Error in factanal(~....

...d add them both to my final error term. I'm constraining two of my parameters (to be between 0 and 1), and so it seems I have to use L-BFGS-B. Unfortunately, when optim gets close to the minimum, it usually bails with 52: "ERROR: ABNORMAL_TERMINATION_IN_LNSRCH" or sometimes 1: "NEW_X". Occasionally it succeeds. I assume this error is something to do with the error terms disappearing when you get reasonably good parameters. Is that plausible? If so does anybody know how to fix it? Thanks, Jon Phillips

...'optim' function to optimise the log-likelihood function. The optimiser seemed to work fine for sample sizes up to 100,000 i.e. the optim function converged, but when I tried to run optim using a sample size of 200,000 the optim failed to converge - the correspoding error message was "NEW_X". Can someone please advise what this error message means, and what I can do to avoid producing this error? I have supplied an extract of my code below for inspection (note that I am fairly new to programming so my code is probably not the most efficient/elegant...). Thank you in advance, S...

Is there a way of removing all rows with missing values from a data frame? I usually use subset(x, var1!="NA") and repeat for each variable. It would be nice to be able to do it in one fell swoop. Also, surprisingly, it doesn't always work. Sometimes I'm left with an empty set even though not all rows have missing values for the variable. Cheers, mikkel Mikkel Grum,

Hello. I seem to be having the same problem that Paul had in the thread titled "[Rd] R 2.15.2 make check failure on 32-bit --with-blas="-lgoto2"" from October of last year <https://stat.ethz.ch/pipermail/r-devel/2012-October/065103.html> Unfortunately, that thread ended without an answer to his last question. Briefly, I am trying to compile an Rblas for Windows NT 32bit

Hello, Sometimes the backend of PVFB knows that it doesn''t need permanent refresh, when the window is minimized for instance (no refresh at all), or the administration tools know that the window is thumnailed, and so a slow refresh rate is fine. Also, some users may want to tune the refresh rate according to the smoothness they would like, balanced with the CPU time that requires.
