The CRAN Taskviews (http://cran.r-project.org/web/packages/Views/) is currently unavailable and returns 404 Object not found! This is possibly due to them now being linked from the side frame and the URL now being http://cran.r-project.org/web/views/ Unfortunately the webmaster link on the 404 page does not have a...

...b sites (tucked away as the third element of a sub-menu of a CRAN mirror site linked to by the CRAN link from the Download menu on the main R home page). The index page is rather plain, so I designed a more engaging one. The result of my effort is now here: http://www.maths.lancs.ac.uk/~rowlings/R/TaskViews/ Having done that, I even considered that something like that could replace the R Homepage. Giving new visitors an idea of the vast range of techniques and application areas available in R would seem to be better than the current graphic which has been there since perhaps 2004. Comments, thought...

Hi, Please what am I doing wrong? I tried installing some views (eg MachineLearning, Multivariate) on R2.15.3, but it keeps on telling me that the package is not available for 2.15.3. Is it true? Thanks [[alternative HTML version deleted]]

...s - a couple of papers in PNAS (lastly:framework for making better predictions by directly estimating variables' predictivity, Lo et al PNAS 2016; 113:14277-14282) have focused interest on mapping complex traits to multiple loci spread all over the genome. I have been around on the relevant taskview(s) I hope but fail to see that the backward haplotype transmission association algorithm (BHTA) first described by the authors in Hum Hered 2002; 53: 197-215. I wonder whether the algorithm has been implemented in R - primarily I ask since I fail to understand exactly how the algorithm works an...

Also https://www.r-project.org/posting-guide.html indicates that RSiteSearch() within R searches R-help but in my install (3.4.3) RSiteSearch() only searches?

I am new to this listand am unable to get the search tools listed on https://stat.ethz.ch/mailman/listinfo/r-help towork. What do people use to search the help archives? 1. The google search box on http://tolstoy.newcastle.edu.au/~rking/R/ returns a 404 error. 2. The http://finzi.psych.upenn.edu/ site has many references but I don't see how to search r-help from there. 3. The

Solved the original problem I wrote in about with a combination of r-cran downloads through Synaptic and downloads from one of the mirror sites. Things worked out well. Using the ctv package I pulled in the contents of the Finance view. Not clear which one, but one of the packages called up RDCOMClient as an apparent dependency. Not showing up as an r-cran file or on any of the mirrors

Hi all, I am wondering if there is a function available in R for simulating spatial distribution of objects (plants in this case) in order to simulate sampling of a population . Specifically, I would like to be able to change the spatial correlation of individuals. I don't want to reinvent the wheel if it already exists. Thanks, Wade

Hi, a collegue has send me an excel sheet with some plasma values, and now he wants to know the AUC steady state. I took a look at the CRAN taskviews, and came up with PK, PKtools, ... The AUC calculation, no problem with that, but how do I calculate the steady state? One way of thinking was with the aid of multiple t-test, to find where we couldn't find difference between the different measuring points, and take this as steady state, but I...

Hi, I'm currently beginning to use R for financial analysis (mainly Basel II benchmarks) and I would like to know if any R-User can give me some initial directions on packages and tutorials which I can use to calculate capital requirements, default probabilities, and related stuff. Thanks in advance, Rick [[alternative HTML version deleted]]

Hello everyone, Can anyone suggest a decently documented (with good examples in the documentation) R package/function that performs segmentation (cluster, mixture modeling) of a population using both continuous and categorical input variables? Thank you, Dan [[alternative HTML version deleted]]

I can plot each county of the contiguous 48 states or all of them using variations of map('county', region=c('wisconsin' . . . .) in the maps package. I was wondering whether similar data was available for Alaska and Hawaii? I was also wondering if there was a database that listed FIPS codes for the counties in Alaska and Hawaii. Similar to 'county.fips'. Thank

I haven't used r in quite a while but would like to get back into it. I have a problem that I would like to solve with r. I have some multinomial data that looks to follow an asymmetric sigmoidal growth pattern. Solving a multinomial gompertz partial differential equation in r is what I’m after. Would anyone be able to provide me the code and packages to do something like this? Regards,

I am a new user and want to learn R from the most basic level. Suggest me a reading or a link. Thanks Varsha P.S. I would appreciate if you could also send me the link where I can read questions and answers posted by others. [[alternative HTML version deleted]]

Dear R users, I would like to perform Latent Class Logit Models for the analysis of choice experiments in environmental valuation. This kind of analysis is usually performed with NLogit Software (http://www.limdep.com). I attach the results I usually obtain using NLogit and NLogit model specifications. For Random parameter models and Logit Models I usually perform my analysis with the package

Hello, trying to locate all the string commands in the base version of R, can't seem to find an area that describes them. I am in need to do some serious parsing of text data to create my dataset. Is there a summary link to all the character operators? string manipulations that would help in parsing text.

I have spatial data on a sphere (the Earth) for which I would like to run an gls model assuming that the errors are autcorrelated, i.e. including a corSpatial correlation in the model specification. In this case the distance metric should be calculated on the sphere, therefore metric = "euclidean" in (for example) corSpher would be incorrect. I would be grateful for help on how to

Hi,   I very recently started using R (as in: last week) and I was wondering if anyone could point me to website(s) with sample code to deal with large datasets (length- and/or breadthwise). I understood that R was never designed to work with datasets larger than, say, a couple of hundred Mb. One way is (as I also read) to let R work in conjunction with SQL. That's one interesting approach
