Re: [R] isssues with predict.coxph, offset, type = "expected", and newdata

Thanks Terry, Re: the second case (predicting from a null model with a newdata= argument), I agree that it looks a bit over the top for such a straight forward computation, so maybe it is more a wish than anything else. In this one instance, this computation is embedded in a wider multi-state

Re: [R] Font problem.

There is R-sig-debian (Ubuntu is a derivative of Debian), but to be honest, this seems more like a question for askubuntu.com. -- Sent from my phone. Please excuse my brevity. On October 2, 2016 1:55:59 PM PDT, Rolf Turner wrote: > >Dunno exactly whom I should ask

Re: [R] Font problem.

Hi Rolf, I would try using dnf (or whatever the Ubuntu equivalent is) to install the X11 fonts. You may have a GUI method for this in Ubuntu. Jim On Mon, Oct 3, 2016 at 7:55 AM, Rolf Turner wrote: > > Dunno exactly whom I should ask about this problem, but I thought

Re: [R] Histogram using Sturges' Bining Errors

Hi Elysa, This is pretty much a guess. If you understand the first error, i.e. that there are nine rows in your input data frame (?) that contain NA, NaN, or Inf values, have you tried manually removing those rows and feeding the remainder to your code? Jim On Sun, Oct 2, 2016 at 7:19 PM, Elysa

Re: [R] BCa confidence bands around fitted curves MARS regression

Hi, So, I can draw/plot the usual 95% least squares confidence bands around the 3 fitted curves for MARS regression, but I don't know how to get the 95% BCa bootstrapped confidence bands. Any help would be highly appreciated. Reproducible example : ## Dataset =

[R] Font problem.

Dunno exactly whom I should ask about this problem, but I thought I'd start with good old r-help. I have recently acquired a new laptop, and have installed Ubuntu 16.04 on it. Still having some teething problems. If I do plot(1:10,ylab=expression(italic(J(r))) I get the error: Error in

[R] Extract an invertible submatrix

Dear R helpers, I am looking for an efficient way to extract (any) one of the biggest invertible submatrix. I have a rectangular matrix A (p x n), with rank k <= min(p, n). I would like to get a submatrix (k x k) invertible, or even better, the list of rows and columns of A which would form

Re: [R] remove a "corrupted file" after using download.file() with R on Windows 7

Hi Henrik, 1. It could be that a virus checker locks the file. This is some internal document so I don't think so and this was monitor by our IT security team. 2. There are Windows software tools that identify which process locks a particular file, e.g. LockHunter (http://lockhunter.com/).

Re: [R] remove a "corrupted file" after using download.file() with R on Windows 7

Hi Robert, sorry for the delays Sometime download.file() failed to download the file and I would like to remove the correspond file. No answers, but a couple of additional questions: 1) Does the issue persist if you close R or does the file remain locked against deletion? no, if I close R

[R] Histogram using Sturges' Bining Errors

Histogram using Sturges' bining Hello, I am trying to create a histogram using Sturges' bining rule, yet I keep getting 2 errors, which probably have to do with the variable I am using. Here is my process and the errors, what would you suggest? k <- ggplot (world, aes (x=polstab)) wid <-

[R] Can I get odd ratios from lm() model or only glm()?

I'm doing logistic regression and I need to infer the coefficients as odds ratios. I first did my model using lm(), but now that I need odd ratios, then should I have used glm() like displayed here: http://r.789695.n4.nabble.com/Odds-ratio-from-Logistic-model-in-R-td2630277.html

Re: [R] Bootstrapping in R

Right. To see it in action just compare the results of the two calls to boot. library(boot) set.seed(1007) x <- rnorm(100) y <- x + rnorm(100) dat <- data.frame(x, y) #Wrong stat1 <- function(DF, f){ model <- lm(DF$y ~ DF$x, data = DF[f,]) #Doesn't bootstrap DF coef(model) }

Re: [R] Convert a list with NULL to a dataframe with NA

It's fairly straightforward with help from the purrr package: library(purrr) map_df(OB1, function(x) { if (length(x) == 0) { data.frame(id=NA_character_, nam=NA_character_, stringsAsFactors=FALSE) } else { data.frame(id=x[1], nam=names(x), stringsAsFactors=FALSE) } }, .id="V1")
