read.table() vs read.delim() any difference??
Hi,
I have a tab seperated file with 206 rows and 30 columns.
I read in the file into R using read.table() function. I checked the dim()
of the data frame created in R, it had only 103 rows (exactly half), 30
columns. Then I tried reading in the file using read.delim() function and
this time the dim() showed to be 206 rows, 30 columns as expected.
Reading the read.table() R-help documentation, I

Modifying a particular column in a tab-delimited file
Hello R users,
Good day!!
I was wondering if there is a way in R to read in a particular column from a tab-delimited file, edit it and write it back into the file with all other columns intact. When I say edit I mean just replacing all the values in that column.
I know to read a particular column from a file using colClasses option in read.delim() function.
Is there any such option to write out

how to test robustness of correlation
Hi, there:
As you all know, correlation is not a very robust procedure. Sometimes
correlation could be driven by a few outliers. There are a few ways to
improve the robustness of correlation (pearson correlation), either by
outlier removal procedure, or resampling technique.
I am wondering if there is any R package or R code that have incorporated
outlier removal or resampling procedure in

Reading sas7bdat files into R
Hi All,
I am trying to import a .sas7bdat file into R.

scientific (statistical) foundation for Y-RANDOMIZATION in regression analysis
Dear all,
I am a statistician doing research in QSAR, building regression models where the dependent variable is a numerical expression of some chemical activity and input variables are chemical descriptors, e.g. molecular weight, number of carbon atoms, etc.
I am building regression models and I am confronted with a widely a technique called Y-RANDOMIZATION for which I have difficulties in

An example of using rJava
I have received a few private emails asking for some simple
demonstration of calling Java code from R using the rJava package
(which can be installed directly inside R). Here is one example for
convolving two vectors (an example in the R manual about linking C with
R).
First write a Java program

multivariate splits
Dear R users!
Does someone know about any algorithms / packages in R, that perform
classification / regression / decision trees using multivariate
splits?
I have done some research, but I found nothing. Packages "tree" and
"rpart" seem only to be able to do CART with univariate splits.
Thank you for your help!

confidence intervals for non-linear regression
Dear all,
I am interested to calculate confidence interval for fitted values in general for non-linear regressions. Lets say we have y=f(x1,x2,..xN) where f() is a non-linear regression. I would like to calculate a confidence interval for new prediction f(a1,..,aN). I am aware of techniques for calculating confidence intervals for coeffiecients in specific non-linear regressions and with them

is gzcon w/ urls not implemented or used differently on linux?
I wrote some code which reads a gzipped text file directly from the web with gzcon(url()) and it works perfectly on OSX, but I cannot get it to work on linux at all, trying several different R versions and linux distributions. Any ideas?

Making heatmaps
Basically, I have the location data for about 1,000 pitches. I can get them
to show up correctly on normal plots, but I am genuinely messed up on
heatmaps.

> location <- as.matrix(location)
Like I said, that can get a plot fine.
Should I use image or heatmap?
