cdplot() with 'POSIXct' x
Hi,
Given that cdplot() is used to produce the conditional density of a
categorical y along a numerical x, it seems natural that it could be
used with a date or time x (such as 'POSIXct'). Is this desirable? If
so, I've created a patch that would allow this, by coercing the POSIXct
x variable to produce the density, but use the original POSIXct x to
draw the x axis.

cdplot error
Fairly new at this.
Trying to create a conditional density plot.
>cdplot(status~harvd.l,data=phy)
Error in cdplot.formula(status~harvd.l,data=phy):
dependent variable should be a factor
What does this error mean? Status is a binary response of infestation (0/1)
and harvd.l is the log of timber harvest density per catchment.
Thanks.

ordered logistic regression - cdplot and polr
Hi,
I have a dataset that I am trying to analyze and plot as an ordered logistic
regression (y = ordinal categories 1-3, x = continuous variable with values
3-9).
First is a problem with cdplot:
Produces a beautiful plot, with the "right" trend, but my independent factor
values are transformed. The factor has values from 3-9, but the plot
produces an x-axis with values from 20-140.

ifelse()
I have a problem with ifelse(), I do not understand how it works.
> X<-c(2,2,1,1,0,0)
> str(X)
num [1:6] 2 2 1 1 0 0
> Y<-ifelse(X>0,1,0)
> Y
[1] 1 1 1 1 0 0
>
Can some one explain what is going on, I do not understand what ifelse is
doing in this case. Can someone explain the output Y.
Thanks

merge two data sets
I would like to merge ?data1 ?that contains 100 unique ID?s with another
data set ?data 2? with 150 ID?s and the age of those individuals ( the ID in
data1 is a subset of the ID in data 2) I would like to merge these data1
with data2 and have the result of the merge to have the ID ordered as in
data1.
Can this be done in R?

Focus problem for shaded windows
Hi,
today, I noticed a problem in focus handling for shaded windows which is
pretty easy to reproduce:
- Disable "Click to focus"
- Shade a window
- Hover another window
- Hover back to the window frame of the shaded window
- Press Ctrl+Alt+S
Expected behaviour would be that the shaded window is unshaded. What
happens is that the last active window is shaded.

help splitting a data frame
Hi All,
I have a dataset that I would like to split based on : or ? ( the data file
is tab delimited) for example:
Ny:23-45 AC
BA:88-91 DB
KJ:21-13 PA
And I would like the data to be splitted and the final results look like
NY 23 45 AC
BA 88 91 DB
KJ 21 13 PA
I would like to have the resulting data as a data frame so each column is a
variable.
Thanks,

breaking a loop in R
Hi All,
I was wondering if there is anything that breaks a loop in R. For example,
For (k in 1:100)
For ( i in 1:10){
If ( condition ){
Break the inner loop
}
}
}
In the above case, if the program runs the if statement, then I want the
inner loop for (i in 1:10) to stop looping and skip the rest of the program.
Thanks for your help

Placing a Shaded Box on a Plot
Hello,
I would like to place shaded boxes on different areas of a
phylogenetic tree plot. Since I can not determine how to find axes on
the phylogenetic tree plot I am not able to place the box over certain
areas. Below is example code for the shaded box that I have tried to
use, and the first four values specify the position.
