Hi R users, Is there a Package in R to - set up a questionnaire? - enter data? Best regards -- View this message in context: http://www.nabble.com/A-package-to-set-up-a-questionnaire---enter-data-tp20947237p20947237.html Sent from the R help mailing list archive at Nabble.com.

We sent questionnaires to lots of folks. The questionnaires differed in word count (wc). For each questionnaire, I know wc and whether the questionnaire was returned or not (status). It looks like there is a fixed rate of return when wc is below a break point, and the rate of return falls off linearly after that. I want to do a piecewise linear regression with two pieces meeting at a common

Hi everyone, I'm stuck on my dissertation which is due next week. I'm a business major student and my project is a comparative research on corporate social responsibility (CSR) between Chinese and German firms. According to my literature review, it's quite obvious that German firms have much better CSR initiatives and strategies than the Chinese ones and I wanted to test whether it was

Dear All, I have worked with R for some time. It's a great tool for data analysis. But it's too hard to inputing raw data manually with R (I don't mean importing data. R is good at importing data). Maybe it's not a focused topic in this list, but I don't know other place where I can ask the question. How do you do when inputing data from a paper material, such as

Hi everyone I have the following problem: My dataframe has 3 variables: ID, Year and and an outcome variable. The dataframe contains repeated measurements because the subjects filled out a questionnaire every year. The time span covers 2 years. Now I want to check if there is a significant change in the outcome over the 2 years with a paired wilcox.test. The problem: Not every subject

Hi, I'm a very fresh newbie to R. My first main question is, what the limitations of R are, what methods can R NOT do, esp. compared to (a) SPSS and (b) SAS? The second question is, how do you handle the data entry, data management and data manipulation in R, to me it seems to be really complicated and confusing?! Are there a kind of "helping tools"? The third question: are

Dear all, I'm struggling to find the best (set of?) function(s) to do repeated measures logistic regression on some data from a psychology experiment. An artificial version of the data I've got is as follows. Firstly, each participant filled in a questionnaire, the result of which is a score. > questionnaire ID Score 1 1 6 2 2 5 3 3 6 4 4 2 ...

Hi, I have a series of id's with multiple visits and questionnaire scores. This is a clinical trial that will be analyzed using the last observation carried forward method. In other words, in order to comply with intent to treat analysis when many subjects withdraw, data points for the last visit must be generated and filled in with the last observation. The ultimate goal is to tabulate the

I'm just learning how to use R right now, so I'm not sure what the most efficient way to organize these data is. I had subjects perform the same task twice with slight changes between the rounds. I want to analyze differences between the rounds. All of the subjects also answered a questionnaire. Putting all of one subject's information on one row seems sloppy. I was thinking about

Dear useRs from the physiology department, Does someone know of an implementation of the SF-36 questionnaire scoring in R? I only found SAS and STATA versions, e.g http://gim.med.ucla.edu/FacultyPages/Hays/util.htm Dieter

Hello! I am doing an analysis on a questionnaire of hunters taken in 4 different districts of some mysterious foreign country. The aim of the study was to gather info on the factors that determine the hunting success of a peculiarly beautiful bird in that area. All variables are factors, i.e. they are variables such as "Use of Guns - yes / no", "Use of Dogs - yes / no" and

Is there available in R a generalized inner product or matrix product, similar to 'outer(x,y, fun)', where one can specifiy an arbitrary function in place of ordinary multiplication? Here's my application. I frequently analyze user questionnaires from our HR/training department. These have questions of the form "please rate your skill in task X", and other questions

Dear list, I have a data file which includes, alongside various variables representing questionnaire scores, a variable for survey weights computed as the number of observations in the sample drawn from that group divided by the number of observations in the population in the group. I need to calculate a covariance matrix of the questionnaire scores for use in sem. How do I apply the weights?

Since R is open source and help may come from varied levels of experience on R-Help, I wonder if it might be helpful to construct a method that can be used to "rate" those who provide help on this list. This is something that is done on other comp lists, like http://www.experts-exchange.com/. I think some of the reasons for this are pretty transparent, but I suppose one reason is that
