similar to: Creating a map in R using ACS PUMS data

Dear List, I have some projects where I use enormous datasets. For instance, the 5% PUMS microdata from the Census Bureau. After deleting cases I may have a dataset with 7 million+ rows and 50+ columns. Will R handle a datafile of this size? If so, how? Thank you in advance, Tom Volscho ************************************ Thomas W. Volscho Graduate Student Dept. of Sociology U-2068

Hi all, I am using ACS micro data (PUMS) with one of the columns as a factor for the place of birth (POBPF). I would like to create a column (POBR) containing a rank corresponding to the place of the observation in the POBPF rankings. For example, if a person is from Oregon, Oregon is the most popular Place of Birth, so each person who came from Oregon should have a 1 in their POBR.

Hi, I am trying to run analyzes incorporating sample weight, strata and cluster (three-stage sample) with PNS data (national health survey) and is giving error. I describe below the commands used. I could not make the code reproducible properly. Thanks, ################################################# library(survey)####change to 0 and 1 variable

Respected all, I am working on a socio-economic survey (named as National Sample Survey in India provided by National Sample Survey Organization, Govt. of India) data of individual as well as households. This is a sample survey where stratified random sapling method has been used to draw samples. The data set uses 'weights' to estimate figures for region, state or

Dear Md Kamruzzaman, To answer your second question first, you could just use the svychisq() function. The difference-of-proportion test is equivalent to a chisquare test for the 2-by-2 table. You don't say how you computed the confidence intervals for the two separate proportions, but if you have their standard errors (and if not, you should be able to infer them from the confidence

I have setup a Zentyal 3.2 Samba4 AD. I am using RSAT to administer the AD server. Windows7 and Linux (CentOS) clients are able to join the AD; uid/gid of directories/files show up as per the definitions in Samba4. With Mac OS X clients, there is a problem. The OS X nodes are able to join the domain (quite a few blogs on this subject). The AD connection shows green button. The AD user is

Hi Biswajit Kar, Take a look at this CRAN Task: https://cran.r-project.org/web/views/OfficialStatistics.html Also, I've been re-writing functions of package "ineq" so that they accept weights. I can provide those if you find them useful. Finally, there are a bunch of packages in CRAN that provide plottings using weights (e.g. "weights", "Hmisc",

Hey, I want to disable the form when an user submits, I know that u can do this with javascript.

Dear folks ? I have a large (26 gig) ASCII flat file in fixed-width format with about 10 million observations of roughly 400 variables. (It is 51 years of Current Population Survey micro data from IPUMS, roughly half the fields for each record). The file was produced by automatic process in response to a data request of mine. The file is not accompanied by a human-readable file giving the

Hi, First, let me thank Jaroslaw for making this survey. I find it quite illuminating. Now the questions: * the #1 solution below (based on cumsum) is numerically unstable. Specifically if you do the runmean on a positive vector you can easily get negative numbers due to rounding errors. Does anyone see a modification which is free of this deficiency? * is it possible to optimize the

We are pleased to announce the release of version 2.1.0 of the "acs" package, now available on CRAN <http://cran.r-project.org/web/packages/acs/index.html>.

Hi all, I've got an old avaya partner acs <7.0 system here. I'd like to add a simple voip bridge so I can hook up our remote offices. From my research, it would seem the pre-7.0 series doesn't have a t1 port, so if I wanted to do this, I would have to feed the avaya system fxs ports from the asterisk box. Does that sound about right? Has anybody ever done this? Does

I'm trying to connect an Asterisk system to an Avaya Partner ACS R6 system. The problem I'm having is that I cannot get the partner system to get CallerID over the T1 modlue. The partner is using the T1 with E & M signalling (which I don't think can be changed), and whatever I tried didn't work. My only option right now is to get FXS ports on the Avaya side plugged into the

Hi, Has anybody tried to get an ACR-38 USB smart card reader working with the devel/pcsc-lite library under FreeBSD? The vendor, Advanced Card Systems, seems to provide a Linux driver with sources, which I could probably port without too much hassle (depending on the license and such) at http://www.acs.com.hk/downloads_drivers.asp#ACR38, but neither that page nor Google nor marc.theaimsgroup.com
