...question this is. I am a Stata user who has begun using R, and the syntax differences still trip me up. The most basic questions, involving as they do general terms, can be the hardest to find solutions for through search. Assume for the moment that I have a dataset that contains seven variables: Pollution, Temp, Industry, Population, Wind, Rain and Wet.days. (This actual dataset is taken from Michael Crawley's "Statistics: An Introduction Using R" and is available as "pollute.txt" in http://www.bio.ic.ac.uk/research/crawley/statistics/data/zipped.zip.) Assume I have attach...

Hello, I am trying to make a correlation matrix in R using cor() and also to get the p-value for each correlation using cor.test(). I can't get these commands to work. I'm getting errors like the following: cor(Pollution, Wet.days) Error in inherits(x, "data.frame") : Object "Wet.days" not found cor("Pollution", "Wet.days") Error in cor("Pollution", "Wet.days") : missing observations in cov/cor In addition: Warning messages: 1: NAs introduced by coercio...

A disturbing behaviour of R: an import of data using RODBC library (Windows 98, R 1.1.1) recognizes accented characters in variables names but these can't be manipulated further. See below: > library(Rodbc) > ch<-odbcConnect("Paradox Files") > pollut<-sqlFetch(ch,Pollutio) > pollut Mortalit? Densit? Pollution 1 82 600 110 2 97 960 140 3 76 570 90 ...... > attach(pollut) > summary(Pollution) Min. 1st Qu. Median Mean 3rd Qu. Max. 90 120 160 160 190...

...mented--I'd like to plot the exact same data in multiple panels but changing the grouping variable each time so that each panel highlights a different feature of the data set. The following code does exactly that with a simple and fabricated air quality data set. dataSet <- data.frame("Pollutant"=c(rep("Black Carbon",5),rep("PM10",5)), "Detector"=c(1:5,1:5), "Value"=c(seq(50,10,-10),seq(100,60,-10)), "Class"="Mass") xyplot( Value ~ Detector | Pollutant, data=dataSet, aspect = 1.0, subscripts=TRUE, panel = functi...

Dear Experts, I am trying to do a time-stratified case-crossover analysis on air pollution data and number of myocardial infarctions. In order to avoid model selection bias, I started with a simple simulation. I'm still not sure if my simulation is right. But the results I get from the "ts-case-crossover" are much more variable than those from a glm. Is this: a...

Today there was a posting by Stefano di Paola to the Web Security Mailing List, http://www.webappsec.org/lists/websecurity about "HTTP Parameter Pollution", with a reference to his and Luca Carettoni presentation at http://www.owasp.org/images/b/ba/AppsecEU09_CarettoniDiPaola_v0.8.pdf The point is that different web servers/backends behave differently when handling requests such as GET /foo?par1=val1&par1=val2 HTTP/1.1 User...

Hallo Everybody How do you specify arguments for a function used within another function? Here is my problem: I am reconstructing a calculator for the burden of disease due to air pollution from publications and tools published by the WHO. The calculations make use of published dose-response relationships for particular health end-points. This is then applied to populations with known or estimated levels of exposure and incidence rates to calcute the number of cases of each end-poi...

...olumn. However, these are organic chemicals (e.g. 1-butene, 2,3,4-trimethylbenzene etc). The package I am going to be using the data with is openair, and many of the great functions require you to specify a column name which does not seem to work with improper column names- e.g. smoothTrend(mydata, pollutant="1-Butene" and smoothTrend(mydata, pollutant=mydata[,"1-Butene"]) I was wondering if there was a function to automatically convert these chemical names (with all sorts of numbers and minuses in the beginning) to something openair can handle? Or am I going to be stuck recodi...

Hi, But "any" rises some other problems well known from S3. One has "any" for "free" in S3. You don't need S4. . But I know how "if" polluted functions look like in S3. They are hard to understand and to maintain. Hence I am quite happy to use S4. Type-checking is usefull if you program with data. Also if you are on the "C side" of the object. A further problem which I have with "any" is, that lm="any&quo...

Avoid declaring ALIGN() and __aligned() in include/uapi/linux/mic_common.h since they pollute user space namespace. Also, mic_aligned_size() can be simply replaced simply by sizeof() since all structures where mic_aligned_size() is used are declared using __attribute__ ((aligned(8))); -- >From mail from H Peter Anvin about this: On Fri, Nov 08, 2013 H Peter Anvin <h.peter.anvin at...

I've finally got SSH compiling for me, but there are a few filenames that conflict with other projects out there (zlib, etc.) and I'm unable to create a monolithic library with SSH without renaming some files. Could you prefix "ssh" to the following files in the next release of OpenSSH. Thanks. crc32,buffer,compress,base64(openbsd file). Thanks again.

Hi List, I am using rsync for hard-link backup. I found that there is a major problem with frequent backup filling up the file system cache with all the data from the files being backed up. The effect is that all the other 'sensible' data in the cache gets thrown out in the process. This is rather unfortunate as the performance of the system becomes very bad after running rsync. Some

I recently had trouble installing the ssl_requirement plugin. script/plugin said it couldn''t find ssl_requirement. I "solved" this by running "script/plugin discover" and accepting the addition of a bunch of other repositories. The script could then discover and install ssl_requirement. BUT: It wasn''t the same version of ssl_requirement that I''d

...ns have already been the source of bizarre bugs, prompting me to use proto like this: > z <- 1 > y <- proto(baseenv(), a=2) > y$z Error in get(x, env = this, inherits = inh) : object 'z' not found It's cumbersome, but it ensures that parent definitions don't pollute my object space; I would rather that be the default behaviour, though.

...ared folders to share mailboxes between users. I have a namespace called "Accounts" that hosts the shared folder for the users (prefix Accounts/%%n/). However, When I issue an IMAP select command on a random non-existent mailbox name under "Accounts", dovecot auto-creates it and pollutes my mail root directory: Python test code snippet: imapConn=imaplib.IMAP4_SSL(serverIP, serverPort) imapConn.login(serverLogin, serverPass) print imapConn.select("Accounts/NonExistentMailbox") imapConn.logout() Resulting in this: drwxr-x--- 1 vmail vmail 4096 Jun 12 10:00 _attachment...

Hi R users,I am a beginner in the use of R. I need urgent help for my thesis study. <https://stats.stackexchange.com/posts/633206/timeline> I have daily air pollution parameters PM10, PM2.5 CO, NO2, SO2, and O3. I also have daily hospital admission numbers. Taking into account the effect of weekends and holidays, I would like to used generalised additive model (GAM) to explore the relationship between daily patients admissions, and air pollution parameters.
