qplot with many files (each one curve)
Hi,
i would like to plot a few hundred .csv files.
Each file contains one curve with x,y values to plot.
I have been searching for "gnu r read many files qplot"
and similar words. I found for loops that use assign to generate
one variable containing a dataframe.
When i uesed the classic "plot' command i could add

anova test for variables with different lengths
Hi all,
I want to test whether the MEAN of two different variables, (and
different number of observations) are the same. I am trying to use the
anova test but it doesn't seem to like that the number of observations
are different:
a=c(1:5)
b=c(1:3)
aov_test=aov(a~b)

predict.zeroinfl not found
Hi Just a quick problem that I hope is simple to resolve. I'm doing some work with zero inflated poisson models using the pscl package. I can build models using zeroinfl and get outputs fom them with no problem, but when I try to use the predict.zeroinfl function, I get Error: could not find function "predict.zeroinfl".
I was using an older version of R, but still had the same

Is there a function that runs AR model with Schwarz Bayesian Information Criteria (BIC)?
Hello,
Is there a function in R by which one can run AR model with Bayesian
Information Criteria (BIC)? To my knowledge, functions ar and ar.ols could
select the order only by AIC.
Thanks,

Welch Two Sample T-Test
I know when I enter this into R:
> x = c(15, 10, 13, 7, 9, 8, 21, 9, 14, 8)
> y = c(15, 14, 12, 8, 14, 7, 16, 10, 15, 12)
> t.test(x,y,alt="less",var.equal=TRUE)
it shows:

A panel of contour plots through a iteration process
Dear all,
as you can see from the code I want to create *a panel of 11 contour
plots through
a iteration process*. I found a thread that address the issue of plotting
many contour.plots in the same device, but it does not address my problem!
I emphasize that the 11 contour plots must be appeared in the same device
through an iteration process and NOT individually!

Simple Likert count data visualization
Hello,
Before I start to construct something inferior myself I would like to know if such a plot function is already out there.
I have count data of a small survey with a few questions which use a scale from "Strongly disagree" to "Strongly agree" and similar things. What I would like to have for a slide is a plot which shows for each question a line over this scale and the

Represent point size according to frequency
Hello! I would like to make a scatterplot of my data, but the problem is that
several points have the same x and y values and are represented as only one
point. I wonder if there is a way to represent the data points, but with
point size representing the frequency of the depicted x-y value?
Thank you!

Combining imputed datasets for analysis using Factor Analysis
Dear R users and developers,
I have a dataset containing 34 variables measured in a survey, which has
some missing items. I would like to conduct a factor analysis of this
data. I tested mi, Amelia, and MissForest as alternative packages in
order to impute the missing data. I now have 5 separate datasets with
the variables I am interested in factor analysing. In my reading of the

about mix type clust algorithm
Hi:
I have tried to find the appropriate clust algorithm for mixed type of data.
The suggested way I see is:
1. use daisy to get the dissimilarity matrix
2. use PAM/hclust by providing the dissimilarity matrix, to get the clusters
but by following this, when the data set grows bigger say 10,000 rows of data, the dissimilarity matrix will be O(n^2), and out of memory will occur.

kruskal.test followed by kruskalmc
Hi all,
After running kruskal.test I have got results (p<0,005) pointing to reject
the hypothesis that the samples were draw from the same population.
Howerver when I run the kruskalmc there are no significant differences in
any of the multiple comparisons. Is that possible? Some clarification?
Thanks, Humber
