Re: [R] tm::stemDocument function not work

Re: [R] Plotting Where People Live on a U.S. Map
Dan, google refine http://goo.gl/AeKml can actually transform zip codes
into longitude/latitude - http://goo.gl/1HDWb will show you how to do this
from street adresses, but it should also work from city names -- i think it
will allocate a default long/lat for a city, but not sure of the exact
mechanism

Re: [R] rrdf package for mac not working
Uwe, sorry for the HTML. In answer to your post: I did try to contact
the developer, no response. but a colleague pointed me to a way out
yesterday through the RCurl and XML packages:
library(RCurl)
library(XML)

query <- "PREFIX sdmx-measure:

accept="application/sparql-results+xml"
results <- getForm(endpoint, .params = c(query=query,accept=accept))

Re: [R] converting a data set to a format for time series analysis
Jim, thanks a lot. This does the trick for dates, but what I have
been struggling the most with is actually the conversion from having
one subject per row to having one month per row. I didn't explain
that well at all in my previous email and so let me try again. The
idea is that the current data set is displayed with one subject per
row. I would like to have it displayed having one hospital per month
per row. For example, the new data set would look like this:
month yearsite number_enrolled_subjectshospital_beds
1 2002 hospitalA 22
300
meaning that hospital A enrolled 22 subjects in 01/2002, and hospital
A has 300 beds -- the beds variable is one variable in a vector that
would display all the covariates for my ARIMA model
your suggestion solved the problem for the dates, but the command I am
looking for now is something that would count the number of subjects
per site per month of a year and then displayed it in the format
above. any thoughts?
I really appreciate your help

[R] converting a data set to a format for time series analysis
I currently have a data set describing human subjects enrolled into an international clinical trial, the name of the hospital enrolling this human subject, the date when the subject was enrolled, and a vector with variables representing characteristics of the site (e.g., number of beds in a hospital). my data sets looks like this: subject hospitaldate_enrollment hospital_beds 1 hospitalA 1/3/2002300 2 hospitalA 1/6/2002300 3 hospitalB 2/4/2002150 4 hospitalC 3/2/2002200 to perform a time series analysis I am now trying to get to a format that would give me the following variables: month yearsitenumber_enrolled_subjectshospital_beds the data would be displayed on one-month intervals, and number of subjects clustered around sites. any help would be greatly appreciate thanks Ricardo __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] diagnostic meta-analyses
List members, has anybody developed functions or formal R packages to conduct meta-analysis of diagnostic tests? What I have in mind is something along the lines of Meta-DiSc (http://www.biomedcentral.com/1471-2288/6/31) thanks Ricardo __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] computational ontology to research questions, and statistical methods
our group at Duke is currently attempting to connect two data sets fed through a web-based system, one containing research questions (i.e., variables positioned with certain roles) and a database of statistical methods. this connection is done informally in a number of R packages and related software such as Rcmdr, R4calc, and Rkward where a variable of a certain type is matched to a certain test. For example, a logistic regression model requires a dichotomous variable as its dependent variable. our goal is to formalize this link through a computational ontology, which would standardize and hopefully facilitate package and library development for R. we have started some parallel efforts regarding both our requirements for this ontology as well a search for existing ontologies. So far we couldn't find any existing ontology, which seems odd given the widespread application such an ontology has Question for the list members: Is anybody aware of any existing ontologies computational focusing on this topic? thanks Ricardo __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Input appreciated: R teaching idea + a way to improve R-
I agree with Frank - decentralization is key in a wiki environment
since it allows the system to dynamically correct itself. That said,
there are some ongoing experiments trying to change this -- check, for
example, http://scholarpedia.org/ , which seems to be somewhat along
the lines Ted described. You will notice that the content is of very
high quality, but apparently the site doesn't seem to expand its
content as fast as other environments that are completely
decentralized.
There is probably not a single answer to this issue, as different
degrees of centralization will serve different purposes to different
audiences in different environments and at different times ... such as
in ecological and evolutionary models

Bill, very interesting comment. However, do you believe that by posting these tutorials on a wiki they could, even if initially faulty, be improved by the community over time?

[R] R and FDA trials
Yesterday I just noticed the new document on R and regulatory aspects for biomedical research posted at http://www.r-project.org/doc/R-FDA.pdf Coming from an institution that performs a large number of clinical trials for FDA and being an advocate of R myself, I have found that the following issues usually come up when discussing the use of R for FDA trials: 1. Most FDA submissions come down to a series of r x k tables, and it is hard to claim that one system is better than another for that. 2. Data is to be submitted to the FDA in SAS (considered by many as the industry standard) or CDISC XML formats (http://www.cdisc.org/); there are pretty good SAS tools for that; does R have comparable? 3. Some packages in R provide acknowledgedly better functionality than their SAS-equivalent, but an entire FDA validation would have to occur each time an enhancement is made to the R package because often an enhancement breaks something else or the syntax would change from one release to another. would be interested in opinions on how to respond to these comments Ricardo __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
