search for: polluted

I apologize for how basic a 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

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

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

R Friends, I'm running R2.7.1 on Windows XP. I'm trying to get some lattice functionality which I have not seen previously documented--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

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. Due to

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

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

Greetings - I am working on some data that contain chemical names with air concentrations, and I am creating a data frame with date/time and each chemical having its own column. 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

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"...

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

I understand why the following happens ($.proto delegates to get, which ascends the parent hierarchy up to globalenv()), but I still find it anti-intuitive: > z <- 1 > y <- proto(a=2) > y$z [1] 1 Although this is well-documented behavior; wouldn't it uphold the principle of least surprise to inherit instead from baseenv() or emptyenv()? (See attached patch.) Spurious

Hi all, I have noticed a strange behavior with dovecot (tested with 2.2.13). I use shared 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

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
