Re: [R] How does once import a function from an imported script?

TeX is not R. You need to (manually) extract whatever R syntax is in the TeX file into an R file. Then you can use the source function to load those definitions into your working environment. I highly recommend reading the posting guide as well. Including the R statements you run and a sample

It's not a problem with your data or use of the functions -- rather I think there's just a little bug in the package (and I've cc'd the maintainer): draw.wd leads to a call of draw.default(type = "l") which in turn leads to plot(type = "l"). However, since draw.default doesn't have a type argument

[R] path.diagram in SEM--display covariances without variances

Forgive me if I'm posting to the wrong placeIt's my first time posting. Here's the situation: I'm using the sem package and making path diagrams using path.diagrams. Suppose I have the following code: #install.packages("ggm") require(ggm) cor = rcorr(7) nm = c("SOF", "IWF", "PWF", "FSC", "FSF

[R] Interpreting Multiple Linear Regression Summary

I would appreciate pointers on what I should read to understand this output: summary(lm(TDS ~ Cond + Ca + Cl + Mg + Na + SO4)) Call: lm(formula = TDS ~ Cond + Ca + Cl + Mg + Na + SO4) Residuals: ALL 1 residuals are 0: no residual degrees of freedom! Coefficients: (6 not defined because of s

Re: [R] Installing binaries from R-Forge

As Uwe said, you need to read the fine manual and set up your system to be able to compile source packages. On Windows that essentially means installing Rtools and Miktek, and configuring some environment variables. --- Jeff

Re: [R] algorithm that iteratively drops columns of a data-frame

Perhaps attach placeholder names to your columns and use those rather than indices? Michael On Wed, Nov 9, 2011 at 10:36 AM, Martin Batholdy wrote: > Dear R-Users, > > > I have a problem with an algorithm that iteratively goes over a data.frame > and exclude n-columns each step based on a stati

[R] Invalid 'yscale' in viewport

I tried Googling for help on this problem, but what I saw only increased my puzzlement. I found a lovely bit of code called esplot() that makes scatterplots with associated histograms and rug plots. I have been trying to use it on my own data, but the viewport routine on which it depends (I think

[R] algorithm that iteratively drops columns of a data-frame

Dear R-Users, I have a problem with an algorithm that iteratively goes over a data.frame and exclude n-columns each step based on a statistical criterion. So that the 'column-space' gets smaller and smaller with each iteration (like when you do stepwise regression). The problem is that in ever

Re: [R] window?

Yes, that will definitely create a time series with the desired frequency, though the actual time index won't correspond to the original so you may need to exercise a little bit of caution in interpreting the outputs of ets(). Glad this could help, Michael On Wed, Nov 9, 2011 at 9:15 AM, wrote:
