ggplot: dodge positions
Dear all,
I want to get a series of boxplots (grouped by two factors) and I want to overlay the original observations and the following code does almost what I want:
library(ggplot)
ddf <- data.frame(x=factor(rep(LETTERS[1:4], each=30)), y = runif(120,0,10), grp = factor(rep(rep(1:3, 10), 4)))
ggplot(ddf, aes(x, y, colour=grp)) + geom_boxplot() + geom_point()
Yet the position of the points

apply: return list of matrices
Hi everybody,
Suppose we have the following data structure:
ddf <-data.frame(a=rep(1:4,3), b=rep(paste("p", 1:3, sep=""), each=4),
c=c(1,0,0,1,1,1,0,1,1,1,1,1))
I want now to make a contingency table for each pair of values of p,
i.e. a contingency table for each of the pairs (p1,p2), (p1,p3) and
(p2,p3). The result should be given as a list of matrices:

ggplot2: legend
Dear all,
I produced the following graph with ggplot which is almost fine, yet I don't like that the legend for "Means" and "Observations" includes a line, though no line is used in the plot for those two (the line for "Overall Mean" on the other hand is wanted):
library(ggplot2)

Hello,

Reconstruction of a "valid" expression within a function
Hello all,
I have some trouble in reconstructing a valid expression within a
function,
here is my question.
I am building a function :

#where DF is a data frame, with Var1, Var2, Fact1, Fact2, Fact3
#and subset would be an expression, eg. Fact3 == 1
#in a first time I want to build a subset from DF

mrds function integratepdf cannot be found
Hi,
Trying to use the function integratepdf of the mrds package, I get this
message:
|Error in integratepdf(fox.ds$ddf$ds$aux$ddfobj, select = rep(TRUE,
nrow(fox.ds$ddf$ds$aux$ddfobj$xmat)), : could not find function

Has anyone already had this issue ? Maybe the function is not exported
in the namespace?
Best,

plotting a function with given formula in ggplot2
Hi All,
I have a scatter plot produced using ggplot2 and I want to add the
regression line to this scatter plot. I suppose I can use
geom_smooth() to do this, but for the sake of learning ( I am new both
to R and ggplot2), I want to try and add it as a function (something
that curve() does in the standard R plotting). I did some search and
found that stat_function() can be used for this. But

Help using "tm" text mining package - preprocessing
Thanks all for your help. I fear text mining is an abstract little corner of
"R".
I have imported 3228 text (.txt) files, each a news story, into R using
[tm]:
textd <- Corpus(DirSource("other/docs"), readerControl = list(reader
=readPlain))
I can pre-process each individual document using tolower(textd[[1]])
however, when I try to run tmTolower() I get a no such command

R results explanation
Hi all,
this might be a stupid question, but still.
Everytime i find some new function it's prettty easy to understand how to
use the syntax and to perform a text. Even the general idea of what the
function does is pretty easy to understand, but i can not find an
explanation (detailed explanation) of the R output for each function. For
example, a function fitdistr() in MASS package i

boxplots with multiple numerical variables
Hi all,
I have a question regarding the boxplot function. The data I am working on has 1 grouping
variable (G) and it has many numerical variables (V1, V2, V3, V4, Vx, etc). What I would like to
do is create a boxplot where the Y-axis represents the numerical values of variable V1...Vx (all
the variables have the same range). The X-axis needs to represent the G-V combination. So suppose

anova statistics in lmer

Copy them to a pastebin and post the link to the pastebin. Pastebin is
