similar to: impossible to invert a spam-object, but possible when it's a matrix-object

The primary error seems to be: "Creating a new generic function for "diff" in "spam" Error in setGeneric(f, where = where) : must supply a function skeleton, explicitly or via an existing function" And the full output follows. Any thoughts on what may be happening and/or how to work around the problem? Thanks! > install.packages('fields')

deaR user, I found an unexpected behaviour of the rms::survplot.survfit function, that is giving me inverted labels for the patient-at-risk rows. The problem is that, for some reason, the survival::summary.survfit function changes the order of two of the suvfit object's strata when called (on my dataset) with the times= option (is this another unexpected behaviour?). survplot takes the

Hello folks, Is there a way to invert the z axis in a 'persp' plot? I tried using 'zlim=rev(range(z))', which would work with 'plot' but does not work in this case. Thank you for your help.

Is there a function in r that let's you efficiently invert a positive definite symmetric Block Toeplitz matrix? My matrices are the covariance matrices of observations of a multivariate time series and can be 1000*1000 or larger. I know the package 'ltsa' which seems to use the Trench algorithm to compute the inverse of a Toeplitz matrix. I am looking for a so to say

Hi! This is probably a very trivial question. Is there an easy way to invert the y-axis (low values on top) when using the function barplot()? Thanks, Jörg [[alternative HTML version deleted]]

Hello, just a simple question How can I do to invert the sign of a number? (for example: -4 to 4, 2 to -2 and so on..) I was looking for a specific function in R but I didn't found it... thank you Francesco -- View this message in context: http://www.nabble.com/Invert-the-sign-of-a-number-tp26110267p26110267.html Sent from the R help mailing list archive at Nabble.com.

Dear R-help list users, I have a huge vector of numbers, how I can invert orden? For example x <- 1:10000000 I would like to obtain x_r <- 10000000:1 Thanks, Sebastian.

Hello, I am drawing some data with ggplot2 and would like to reverse the order of the y axis and set a custom range for it. I can do the former but when I add the key `limits` to `scale_y_reverse` I get an error as shows below and, worse, no data shown in the plot. How can I properly set a reverse y scale with a defined range in ggplot2? Thank you ``` A <- rep(c(0, 3, 6, 12, 24), 3) B <-

Hi! I am using R to process some community survey data. Several item responses are recorded via a 7-point Likert-Scale. As I have coded the responses, 1 represents high agreement, and 7 high disagreement. This of course impacts the coefficients in a linear regression (of example agreement to self-perception measures on housing satisfaction). For some purposes, in order to make the coefficients

Dear List, I am using the wireframe function in the lattice package, and I am wondering if it is possible to invert the default axes orientation for x and y axes... what parameter should I look for? Best regards, Simone Gabbriellini
