[gov2001-l] party

by king＠harvard.edu

Hi everyone. I'd like to have you all over to my house for an end of year party on Saturday May 10th at noon. Please feel free to bring a guest, kids, etc. We've got 2 dogs, in case that's an issue for anyone. We live in Brookline about 5 miles from HU, and easy to get to by Bus, T, or car. Directions are at this hidden link: http://gking.harvard.edu/directions I'd appreciate if you'd RSVP soon, by responding to me and my assistant Bev who I've CC'd, so we can get a count for food. Let me know whether you can make it and if you'll be bringing someone. I hope to see you there. Gary

[gov2001-l] gov2001-l Digest, Vol 40, Issue 20

by blmichel＠fas.harvard.edu

Hi all, I'm having trouble installing MatchIt, or more specifically, lpSolve... it looks like the Mac binary isn't working (according to CRAN), though I had it working last week before I updated R to 2.7.0... I get the following error when installing from the source: gcc -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.4 -std=gnu99 -I/Library/Frameworks/R.framework/Resources/include -I/Library/Frameworks/R.framework/Resources/include/ppc -I/usr/local/include -I . -DINTEGERTIME -DPARSER_LP -DBUILDING_FOR_R -DYY_NEVER_INTERACTIVE -DUSRDLL -DCLOCKTIME -DRoleIsExternalInvEngine -DINVERSE_ACTIVE=INVERSE_LUSOL -DINLINE=static -DParanoia -fPIC -g -O2 -c lpslink55.c -o lpslink55.o lpslink55.c:11:20: error: malloc.h: No such file or directory make: *** [lpslink55.o] Error 1 chmod: /Library/Frameworks/R.framework/Versions/2.7/Resources/library/lpSolve/libs/ppc/*: No such file or directory ERROR: compilation failed for package 'lpSolve' Any thoughts? Thanks, Ben

[gov2001-l] setx() and sim() on Amelia datasets

by brown4＠fas.harvard.edu

Just to double check, when I run the setx() and then the sim() command on a dataset that is an mi()'ed version of Amelia datasets, is Zelig automatically creating the 1/m number of simulations from each constituent dataset and making the necessary mathematical corrections? As in such a case: Zelig.Imputed <- mi(out1,out2,out3,out4,out5) ruler <- seq(0,1,0.005) my.model <- zelig(dprotestmar.max4~dlprotestmar.max4+polity2l+provcont+eprovcont, model = "logit", data = Zelig.Imputed) x.out <- setx(my.model, provcont=ruler, eprovcont=3) s.out <- sim(my.model, x=x.out) Thanks! -Colin

[gov2001-l] Problem Set - Paper Copy

by brown4＠fas.harvard.edu

Jen(n|s), Does a paper copy of the problem set need to be submitted for those of us who normally submit paper copies, or should we just submit the PDF to the dropbox? Thanks! -Colin

[gov2001-l] Clarification

by mmccull＠fas.harvard.edu

Hi, I am a little confused about the wording in Q1, Part C: For the counterfactual dataset, are we supposed to switch all import observations, where a 1 becomes 0 and a 0 becomes 1, or are we just supposed to switch all the 0's to 1's per #2 in Part B?

[gov2001-l] Saving the workspace in Emacs/ saving objects as files?

by john.sheffield＠gmail.com

We have a massive output file that took hours to run (a list of R objects). How do we save it? And how do we save the workspace? I'm working on the servers... Thanks! John

[gov2001-l] Sorting a data frame

by john.sheffield＠gmail.com

Silly question: How does one sort a dataframe such that it only sorts on the characteristics of the first column and preserves each row as an intact unit? I.e., I have a vector of propensity scores in column one that I want sorted, but the propensity score corresponds to other variables in columns 2-8 that must remain connected to those scores. Thanks!

[gov2001-l] Simulation with multiply imputed data sets

by blcarter＠fas.harvard.edu

Hi everyone, I have a quick question. I'm working with several multiply imputed data sets and would like to simulate quantities of interest at mean/mode values of explanatory variables. Because of the way I subset data iteratively in a for loop, I would like to consolidate the five data sets into a single data set, with each observation simply taking the mean (or, in some cases, mode) value of the five data cells from the imputed data sets. So my question: How can I coerce the five imputed data sets into a single data set with mean/mode values? There must be some straightforward way to do this. Thanks in advance for the help. Best, Brett

[gov2001-l] mysterious Zelig error

by keith.schnakenberg＠gmail.com

I've been trying to figure this out for a little while. When I try to estimate my model in Zelig, I get: > model <- zelig(immpol ~ LABOR + IDEO + INCOME + WHITE + BLACK + ASIAN + HISP + EDUC + AGE + SEX + secon + pecon + jobhard + UNEMPLOY + ifriend + iarea, model="ls", data=pew) Error in data.frame(RESP = c(1, 6, 7, 8, 9, 10, 11, 12, 13, 15, 17, 18, : arguments imply differing number of rows: 6003, 0 Even though: > length(pew$immpol); length(pew$LABOR); length(pew$IDEO); length(pew $INCOME); length(pew$WHITE); length(pew$BLACK); length(pew$ASIAN); length(pew$HISP); length(pew$EDUC); length(pew$AGE); length(pew$SEX); length(pew$secon); length(pew$pecon); length(pew$jobhard); length(pew $UNEMPLOY); length(pew$ifriend); length(pew$iarea) [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 [1] 6003 Does anyone have a theory as to what could be going on here? Thanks, Keith
