Thanks Bert, I think we agree on the current behaviour, but I'm still not sure if it's desirable. The mode isn't used for method dispatch. In the following example, I have to write `log.foo` in order for the correct method to be called. > x <- seq.int(5) > class(x) <- c("integer", "foo") > half <- function(x) UseMethod("half") >

I would expect that several math operations should always return values with a class of numeric. If the input is defined with multiple classes, however, the class attribute is preserved. I would think this may have some unintended side-effects. Here's an example: > sessionInfo()$R.version$version.string [1] "R version 3.4.0 (2017-04-21)" > x <- seq.int(5) >

I think you may be confusing (S3) class and ?mode. > x <- seq.int(1:3) > class(x) [1] "integer" > mode(x) [1] "numeric" > class(x+.5) ## coercion [1] "numeric" > mode(x+.5) [1] "numeric" But note: > y <- as.integer(1) > class(y) [1] "integer" > class(y) <- "foo" > mode(y) [1] "numeric" >

Lattice experts: Can you think of a way to produce a levelplot as below and then add a histogram of the z variable to the top margin of the plot that would sit on top of the color key? x <- seq(pi/4, 5 * pi, length.out = 100) y <- seq(pi/4, 5 * pi, length.out = 100) r <- as.vector(sqrt(outer(x^2, y^2, "+"))) grid <- expand.grid(x=x, y=y) grid$z <- cos(r^2) *

Dear List members, its me again, fighting with lattice graphics. I am trying to plot a world map, add some points on different locations with different colors and add a legend, but did not succeed yet with the legend. Here is my code: library(fields) # Data for demonstration data_x = c(0,50,60) data_y = c(0,0,0) cols???= c(1,2,3) data(world.dat) #print map all=xyplot(world.dat$y? ~

Howdy, I have done many searches and can't seem to find a way around this. I am reading in a .csv file where each row is a dataset and each column represents a position. The values are sparse (there are 2003 positions but usually only 100-200 values) and the idea is to be able to plot each dataset (row) and overlay them in different combinations. What I would like to do is have a plot

Thanks to the lattice gurus on this list, and having reference to the excellent open-access Sarkar 2008 ISBN 978-0-387-75968-5 e-ISBN 978-0-387-75969-2 http://dx.doi.org/10.1007/978-0-387-75969-2 I now know how to label lattice panels by variable value: see thread starting @ https://stat.ethz.ch/pipermail/r-help/2012-November/329450.html (and demonstrated below). This allows me to use

Hallo, The command: x <- 3 mat <- as.matrix(expand.grid(rep(list(0:1), x))) generates a matrix with 2^x columns containing the binary representations of the decimals from 0 to (2^x-1), here from 0 to 7. But the rows are not sorted in this order. How can sort the rows the ascending order of the decimals they represent, preferably without a function which converts binaries to decimals

Has anyone had any experience with making calls to Win32 COM object in a rails controller. I have no problem making the calls using the WIN32 module, however I do seem to have some memory leaks, when the COM object being called at some point makes use of SafeArrays. The same method calls in VB,Visual C++ don''t produce the same memory leaks. I realize this might seem a little odd, but

You need to extend docs/schemas/domaincommon.rng which is what is used for the validation virsh is reporting. Do a 'git log' on that file for other examples of patches adding new qemu command line options.

Thanks Cole. I need to use network type="ethernet" with LXC instead of Qemu. I have reopened my bug.

The documentation of ?lapply includes: > lapply and vapply are primitive functions. However, both evaluate to FALSE in `is.primitive()`: is.primitive(vapply) #FALSE is.primitive(lapply) #FALSE It appears that they are not primitives and that the documentation might be outdated.
