I am hoping for some advice on the following matters. I have a csv data file with 153 variables x 92 rows. To determine what the variables looked like I ran the summary command. One variable had a large number of missing values 54/92. For some reason, all subsequent 74 variables are reported as having 92 NA values, irrespective of whether the original csv variable was complete or not.

I am hoping for some assistance with a problem that has puzzled me. Immediately below is the error messages I obtained when I tried to perform two functions. (A) tapply(outcome,na.rm=T,grp,mean) Error in tapply(outcome, na.rm = T, grp, mean) : arguments must have same length +++++++++++++++++++++++++++++++++++++++++++++++ (B) library(nlme) > anova(lme(outcome ~ grp * time,

I want to compute a new variable (newvar) based on the values of two other variables (t1freq, t2freq).The two variables (t1freq,t2freq) are contained in a dataframe - study1dat <- read.csv("c:\\study1rb.csv",header=T) . I gather this computation can be done using Apply and I have run the following example from the help menu ## Compute row and column sums for a matrix: x

Hi I'm trying to extract complete rows from a dataframe by group based on the maximum in a column within that group. Thus I have a dataframe: cvd_basestudy ... es_time ... _____________ study1 ... 0.3091667 study2 ... 0.3091667 study2 ... 0.2625000 study3 ... 0.3033333 study3 ... 0.2625000 __________ etc I can extract the basestudy and the max(es_time)

I am a novice R user, and I am having difficulty understanding R's influence plots. I am trying to remove outliers from a particular variable, "sib." I am able to generate influence plots and further outlier information such as below (which is a shortened example). For my analyses, I end up excluding the points R refers to, 7, 18, 26, and 105. However, my question is, how can I

Hi. I have the following problem. I use by() to compute a table of observed and expected counts of a variable (eg sobjects who belong to a smoking category) within combination of 4 factors (age class, education, sex, region) for a total 4*3*2*5 tables. I get a list of length 120 and dim 4. Noww I want to sum the tables within the level of one of the grouping variables, eg age class. How can I

I''ve been using acts_as_ferret for a couple of months now. Everything was going fine. Suddenly, however, when I try to rebuild my index, only 1 of the 2 models I index gets indexed correctly. Looking in the ferret_server logs, it says that both were successfully rebuilt. However, one of the indexes has no data in the folder. The other was index correctly. The odd thing is that this only

Anyone successfully used a calendar control? I''d like to emulate the calendar control seen in "Google Calendar". What do you recommend as a good calendar control? Thanks, Chris -- Posted via http://www.ruby-forum.com/.

Has anyone had success getting OpenLDAP > 2.1.22 to work with Samba and ADS. I can get 2.1.22 to work with Samba 3.0.x. If I try a newer version, it barfs when it calls ldap_set_option in function ads_do_search. I've tried with 3.0.14a and 3.0.20pre2. They changed how OpenLDAP interacts with Kerberos after 2.1.23. I did exchange some emails with the OpenLDAP developers. It wasn't

Hi, I recently bootstrapped gcc4 frontend on a i686-linux-gnu too. As I notice, if the llvm "tools-only " was build with srcdir != objdir , the building of llvm-gcc4-1.7.source encountered mistakes of unable to find some header files. So I just edited llvm-gcc4-1.7.source/gcc/Makefile.in and a line like this: INCLUDES += -I$(LLVMOBJDIR)/include With this change, the building errors

Hello, Andrew, > I have checked by libstdc++, with a higher version: > > [wuxi at ppidellsc1420 lib]$ rpm -q libstdc++ > > libstdc++-4.1.1-52.el5 It is lower version. You should use newer version (the one, you've built during gcc 4.2.3 compilation) for the binaries built with new compiler. There are two solutions: 1. Build new gcc with --disable-shared, which will
