rearrange data: one line per subject, one column per condition
...2 1076.152857 76.152857
...
I know its possible the other way around. But that's not what I need (this time).
Before anyone asks: Yes, I want to do some analysis on my data in SPSS, so I need the rearranged format.
Regards and Thanks,
Dieter

Smoothing a path in 2D
...present a trajectory in space.
For example, I have an ordered (=time) set of (x,y) tuples which
constitute a path in a 2D space.
Is there a way using R to interpolate between these points in a way
similar to spline interpolation so that I get a smooth path in space?
Greetings,
Dieter

barplot2(RT,beside=T,col=c('black','white'),ylim=c(500,1000))
Does anybody know of a solution?

Making a table: collapsing across sub-strings
...ed in the count of 'ababaaa' and should not
be listed as a separate entry in the frequency table.
Does somebody has a pointer to a way to do this? I have been checking
out the CRAN packages for handling DNA sequences, but this has not
really brought me closer to a solution.
Thanks,
Dieter Vanderelst

lineplot.CI problem
.../MarkerMe/example.png
So, has anybody experienced this problem and solved it before? I think I could try padding the data of the second case with zeros to eliminate the missing data. But I hope there is a better solution.

Kruskal's MDS results
...imensional Scaling algorithm (isoMDS, MASS package).
The 'goodness of fit' is reported as "The final stress achieved (in percent)".
What does this mean exactly? I've tried to google for an answer but I've not come up with a definitive answer.

cumulative frequency plots for factors
Dear list,
I have a data frame with a number of events (factor) and the times at which they occurred (continuous variable):
event time
A 10
A 12
B 15
A 17
C 13
...
Is it possible in R to make a plot against time of the cumulative frequency of occurrence of each event? This would be, a raising line for each factor.

Combine graphical and textual output
Hi,
I would like to know whether anybody knows a simple way to combine
textual and graphical output in R.
A typical analysis produces textual output (e.g. model fits) and plots
in R. I would like to know whether R has the possibility of combining
these into a single 'report' or output. An example of a program that
does this is SPSS. After running the analysis you have a combination

comparing mixture models (mix function in mixdist package)
...However, we were wondering whether there are methods that can be used to compare models that differ in the number of distributions fitted and/or the shape of the distributions.
Is there a way, using likelihoods maybe, to compare this kinds of fits in a statistical meaningfull way?

interp() function output not continue
Dear List,
I'm using interp() to prepare 3d data for plotting with the contour() function.
If have x,y and z data. All are arrays. X and Y are sampled in an orderly fashion on a grid (a circular sub-area of a grid - see plot). I'm trying to use interp() to get x and y arrays and a z matrix that can be fed to contour().
This is the command:

ggplot2 barplot: extra markers in graph
Dear List,
(self-contained example + version info at the bottom)
I'm having trouble producing a barplot using the functions in ggplot2. When I use the position="dodge" option, the bars are plotted but also a number of spurious markers. More specifically, a number of black dots are plotted in the graph that should not be there. This behaviour is not seen when calling the same

re-arranging unsorted data for surface/contour plot
Hi list,
I'm struggling with plotting a 3d data set.
I have a data frame with x,y and z values. They occur in no particular order (ie x and y are not ordered).
However, I want to visualize the data using a contour plot.
Now, the x,y and z data going into contour() are supposed to be ordered.
My question is: Is their a quick way to re-arrange my data such that it can be fed to contour()?

prior covariance in Mclust
Hello,
I'm trying to use Mclust to fit a Gaussian Mixture Model to a
mulitdimensional data set.
Because of the specific source of my data, I know that all components
have the same variance and that the covariance between dimensions is
zero (modelname=VII).
Furthermore, I have a reliable estimate of the variance of the components.
I want to to use this estimate as a prior in mclust, hoping
