[R] segments within a lattice graph

Hi, I would like to use the segments command within a lattice graph. Is this allowed in R in the same way as in SPlus? If not, what is the alternative? For example, the following produces vertical line segments between points in SPlus but in R the line segments are not shown. (I want to

[R] Greek Letters for labeling persp-axis

Hi everybody, on ?plotmath it can be seen that mathematical expressions like a greek letter could not be used for x- and y-axis labels in 'persp' plots. Unfortunately, this is exactly what I want to do: I need an expression(rho) to label the y-axes. Does anybody know a way to solve the problem.

Re: [R] Removing autocorrelations

This makes no statistical sense. If you are going to perform a regression on a time series (and if it has any point so there is a significant regression) then if the regressor is autocorrelated the response will be too even with independent errors. You need to do the regression and the modelling

Re: [R] as.POSIXct problem -- summary

A summary on this: 1) RedHat 8.0 contains an unreleased version of glibc between the released versions 2.2.5 and 2.3. That version (and =2.3) have been modified to make dates prior to 1970-01-01 invalid in some cases but not others. We've put a workaround for this in R 1.6.2 (due on Friday),

[R] Re - segments within a lattice graph

Hi, The solution to my problem is to use 'lsegments' instead of 'segments' within lattice commands. (Although I wont forget again, a comment in the segments help file referring to 'lsegments' might help others not to make the same mistake in the future.) My thanks to Renaud Lancelot.

[R] how to save envir. when batch is halted

Dear R-users, If for whatever reason a batch execution of my script halts I want R to save my current environment, along with .Traceback var, in the .RData file (in other words I need something like core dump). It seems however that if execution is halted via stop() no .RData file is dumped. So

[R] help interpreting output?

Dear R experts, I'm hoping someone can help me to interpret the results of building gam's with mgcv in R. Below are summaries of two gam's based on the same dataset. The first gam (named gam.mod) has six predictor variables. The second gam (named gam.mod2) is exactly the same except it is

[R] plot()

I am an R novice trying to figure out plot(). Specifically, I am trying to plot the values of a numeric variable V for a set of years (1970, 1974, 1976, 1978, 1980). How do I get R to label the years I am plotting on the x-axis rather then some general levels (1970, 1975, 1980.) Using

Re: [R] plot()

try text(c(1970, 1978, 1990), x=1:3, y=1:3) after you first call plot(c(1, 3), c(1, 3), axes=F, type=n, xlab=, ylab=) to set the plotting area. Yuelin. -- From: Nirmala Ravishankar [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [R] plot() Date: Mon, 6 Jan 2003 20:19:58 -0800 (PST)

Re: [R] plot()

First, it is usual to make plots with generic scales rather than label each of the x values used, especially when they are irregularly spaced (as here). But if you want to do that, use axis() to create your own axis. Here's a test y - data.frame(year=c(1970, 1974, 1976, 1978, 1980), V=rnorm(5))
