Dear R experts, I had a question which may not be directly relevant to R but I will be grateful if you can give me some advices. I ran a two-level multilevel model for data with repeated measurements over time, i.e. level-1 the repeated measures and level-2 subjects. I could not get convergence using lme(), so I tried MLwiN, which eventually showed the level-2 variances (random effects for

Dear R users, If anyone can tell me how to extract the p values from the output of gee? Many thanks in advance. Yu-Kang _________________________________________________________________ §K¶O¸ÕÅ¥ MSN ­^»y¾Ç²ß¡G©M¯u¤H¦Ñ®v½u¤W¾Ç­^¤å http://www.msn.com.tw/english/

Dear R users, I used the multivariate random numbers generation function in MASS for my study. I wonder what is an approriate way to cite the library and its authors in my publication to express my gratefulness? best regards, Yu-Kang

Dear R-ers, In my question there are no statistics involved - it's all about data manipulation in R. I am trying to write a code that should replace what's currently being done in SAS and SPSS. Or, at least, I am trying to show to my colleagues R is not much worse than SAS/SPSS for the task at hand. I've written a code that works but it's too slow. Probably because it's

Dear R-users, I am a dentist (so forgive me if my question looks stupid) and came across a problem when I did simulations to compare a few single level and two level regressions. The simulations were interrupted and an error message came out like 'Error in MEestimate(lmeSt, grps) : Singularity in backsolve at level 0, block 1'. My collegue suggested that this might be due to my codes

Using the survival library, it is possible to get a plot of all the subjects in a sample and it is possible to get a plot of all subgroups in the same plot. How does one get a separate plot for each subgroup? plot(survfit(Surv(time,death==1)~group),col=1:10) The above results in a hideous graphic representation. I would prefer to specify par(mfrow = c(2, 5)) and have each plot separately --

Hello. I know how to make a bar plot in which a numeric y variable is plotted against some grouping variable X (say, groups A, B, C) when this grouping variable is subdivided into each of two subgroups; so the bars would be: (group A subgroup 1) beside (group A subgroup 2), then (group B subgroup 1) beside (group B subgroup 2), and so on. This is done using the beside=TRUE argument in the

Hello! If I run this example: library(nlme) fm1 <- lme(distance ~ age+Sex, Orthodont, random = ~ age + Sex| Subject) If I run: summary(fm1) then I can see the fixed effects for age and sex (17.7 for intercept, 0.66 for age, and -1.66 for SexFemale) If I run: ranef(fm1) Then it looks like it's producing the random effects for each subgroup (in this example - each subject). For example,

Hello, I'm using the rmeta package to perform a meta analysis using summary statistics rather than raw data, and would like to analyze the effects in three different subgroups of my data. Furthermore, I'd like to plot this on one forest plot, with corresponding summary weighted averages of the effects displayed beneath each subgroup. I am able to generate the subgroup analyses by simply

I have a nice hierarchical table structure like this: divisions has_many groups groups belongs_to division has_many subgroups subgroups belongs_to group has_many units units belongs_to subgroup I have a report which is based on units, but i want to be able to filter the units by which subgroup, or which group, or which division. I also want to sort them by division.name,then group.name,

Dear R users, Can anyone tell me how to get the p value out of the output from summary.manova? I tried all the methods I can think of, but failed.

Hello everybody I am trying to extract some observations from a data frame, ie the subjects that belong to a given group, and although t-test etc work if I try to obtain the number of subjects in the subgroup i get some funny numbers. All the subjects with NA for group are included in the subgroups 'group==1' etc. Is this a bug? for example in Windoze R : Copyright 2001, The R

Hi there, Could someone help me with the following programming problem..? I have written a function that works for my intended purpose, but it is quite closely tied to a particular dataframe and the names of the variables in this dataframe. However, I'd like to use the same function for different dataframes and variables. My problem is that I'm not quite sure how to tell my function in

I'm trying to collapse the following table along the sub-group factor. In this case, collapsing means taking the average ages within a subgroup and creating a new table. I seem to be running into trouble trying to create this new data frame. I can use the ave() function to find averages within a subgroup but how do I maintain the Group/Gender factors after collapsing? (see bottom table) Can

Hi friends, Please help me with this bug. *Bug in my code:* In this variable sub_grp_whr_cls_data[sbgrp_no,1] I store the where clause.every sub group has a where condition linked with it. Database1 Where clause was not found for a particular subgroup, sub_grp_whr_cls_data[sbgrp_no,1] value was NULL So the condition (*sub_grp_whr_cls_data[sbgrp_no,1]=="NULL" ||

Dear R experts, I want to extract standard error from the output of lme, but I found fix.effects() does not include SE of the coefficients. Many thanks in advance.

With this mail I would like to make a proposal to add additional informations to the core and plugin metadata files. Currently these tags are already handled in the ccs configuration system. Ccs automatically adds this informations to the core/plugin option set, but I think that it would make more sense to add this to the official files, to allow similar features in other configuration

Hi, Is there is any way in ruby on rails where we show all my groups there subgroups with check boxes in tree structure way? e.g group A | ----Group A.1 | ----Group A.2 | ---------Group A.2.1 All with check boxes and subgroup opens when click on root ? -- Posted via
