Fitting distribution in range
Hello.
I am trying to fit my data sample x with different distributions such that
the integral from min(x) to max(x) of the fitted distribution will be one.
Therefore I have wrote my own log-likelihood functions and then I am using
mle {stats4}. So, for example:
ll_gamma <- function(a,b) {
integrand <- function(y){dgamma(y, shape=a, rate=b)}

Hi list,
I was using Sweave and was wondering if anyone has had any luck changing the font colors of the code chunks. For instance, in my .Rnw preample I tried including:

\definecolor{darkred}{rgb}{0.545,0,0}
\definecolor{midnightblue}{rgb}{0.098,0.098,0.439}

Help Required in using cast (reshape package) function
Hello everyone,
I am new to R. I have data in the form of excel pivot table format and I
want to cast it into a format which can make it compatible with
computation.
Since I already have the package in pivot format; I avoid melt function
and use the cast directly.

Case statement in sqldf
2018-03-3 in your code should be 2018-03-31.
The line
then'201415'
needs to be fixed.
When posting please provide minimal self-contained examples. There was
no input provided and library statements not relevant to the posted
code were included.
Fixing the invalid date and bad line, getting rid of those library
statements that are unnecessary and providing some test input, it

lattice, xyplot, using "panel.segments" by just addressing one panel
Hi R experts,
I'm using the xyplot function in lattice to draw a multipanel plot consiting
of 5x6 scatterplots.
Now I need to link single points in each of those scatterplots (=panel),but
the points, that need linking are different for each panel.
I tried to use the panel.segments function for that, but I can't address
each panel separately. Links right for panel 1, show up in all other

I would like to figure out a better way to label the horizontal abline.
I tried multiplying the text y position by a scale, but this didn't always put the text in a useful position. I guess I am curious if there is a preferred procedure for labeling the

Hi Eric,
you can use an annotate-layer, eg
ind<-which(sig>0,arr.ind = T)

rpart error with 0-frequency factor levels (with partial fix) (PR#1378)
(I'm sending to r-bugs because rpart is one of the recommended packages and
is always installed. I'm also sending it directly to Dr. Ripley, as the
maintainer.)
rpart working as a classifier does not work (produces no splits) when the
class indicator has no instances of one of the factor levels, as long as the
factor level is not the final level. I have at least a partial fix, which I

R Commander and FactoMineR
Dear Users,
I helped to install R Commander and FactoMineR to one of my collegaues.
