[R] R Example scripts

A few years ago R changed the way help was handled so that the HTML files are no longer available in the library directory. Around that time the R example files that used to be in some of the libraries also vanished. I'm wondering where the "r-ex" folder went. Is it totally unsupported and gone?

Re: [R] problem with pip2d() from ptinpoly

Apparently it matters whether your polygon is defined clockwise or counterclockwise. A point outside your triangle is recognized ... > q2 <- matrix(c(594893.0,115435.0), ncol=2, byrow=T) > pip2d(Vertices = verts, Queries = q2) [1] 1 ... and defining the triangle in counterclockwise sense gives

[R] problem with pip2d() from ptinpoly

Hi, pip2d() doesn't seem to work correctly for me. I have a plot of a triangle that a query point fits inside, but the point is defined as outside the polygon by pip2d. library(ptinpoly) verts <- matrix(c(594891,115309,59,117201,594891,117201), ncol=2, byrow=T) query <- matrix(c(594885.0

Re: [R] Extracting Width and Length of Each Shape in EPS File

How are we supposed to know what you are capable of? Regardless of the answer to that, I strongly suspect that you would not find that the effort required would yield a result worth your effort. R is really an interpreted language, so your ".exe" would just be calling the R interpreter for you..

Hi. I am new to POSIX and I'd like to understand the reason of this difference. dt1 = as.POSIXct("2014-03-29 09.00", format="%Y-%m-%d %H.%M") dt2 = as.POSIXct("2014-03-30 09.00", format="%Y-%m-%d %H.%M") dt2-dt1 > dt1[1] "2014-03-29 09:00:00 CET"> dt2[1] "2014-03-30 09:00:00 CEST"> dt2-dt1 Time

[R] Mediation with multilevel data - Random slopes or not?

Hi, I have been using the mediation package in R to test for mediation in multilevel data. My data is as follows: X: continuous, M: binary, and Y: binary (Y:outcome, M: mediator) I'm testing a 1-1-1 mediation. I get different results when I use random slopes in the equations and when I don't. My
