Hi
Why you are so reluctant to use dput for sending us part of your data?
The result of str indicates that that SCH_TIME is character vector in which
some values are time and others are **empty** strings. But empty string does
not mean it is missing string.

Frank,
I don't think there is any way to "fix" your problem except the way that I
did it.

Hi,
I want to plot a line graph using this data. IDX is x-axis and V1 is y-axis. I
also want standard error bars and 99% CI to be shown. My code is given below.
The section that plots the graph is the problem. I don't see all the points in
the line graph with error bars. How can I also show t

Version 3.0-0 of bayesm is now on CRAN.
All MCMC routines in this version have been recoded using rcpp-Armadillo.
This results in speeds gains
of between 2 and 30 times faster (hierarchical and density estimation
routines are on the higher end of this range) than
in bayesm version 2.2-5.

Dear all,
I am trying to generate boxplots by giving a shapefile and an image as
input. The shapefile takes the pixel values from the image and shows
the distribution of pixels in the form of a boxplot.
Can somebody please tell me how I can execute this in R?
Many thanks!

You can find details about packages which support meta-analysis in R in

Your workflow in principle is:
- read the image into an object for which you can obtain values-per-pixel in a
2D structure;
- read the shapefile and convert into a polygon;
- determine the bounding box of the polygon;
- use the inout() function of the splancs package to get a list of booleans for
I'm trying to do the following: search each patient's list of diagnoses for a
specific code then create a new column based upon the the presence of the
specific code.
Simplified data follows:

2 734 311
This faster than your version, and doesn't return NA:
df$htn <- apply(df[,2:4], 1, function(x)any(grepl("^410", x)))

No, you got a file packagename_version.zip.
Now,
Thank you very much Terry. I'm still puzzled at why this worked a year
ago. What changed? I'd very much like to reverse the change by setting
an argument somewhere or manipulating the terms object.
I echo your sentiments about the general approach.

Hi friends,
Im trying to make a model selection comparing models built with "lm" function
(package "stats") and "lme" function (package "nlme"). Do you know if there is
a problem to compare these models with the function "AICtab" (package "bbmle).
Thanks!!! Bruno Cid Crespo GuimarãesMestre em
Hello R users,
I encountered a strange problem while writing a package that uses the
nlme function. First, I wrote some code that uses the nlme function,
and it ran without errors. However, when I tried to put the code into
a package, the nlme function was unable to locate a function that was
