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

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

The dataframe contains repeated measurements because the subjects filled out a questionnaire every year. The time span covers 2 years.

I have been inputting my data into text files using a text editor on a Windows 2000 PC. I would like to create a front end form that does validation on the fly to reduce the errors in my input and make it possible for family members that are not into computers to help me out with data input tasks. I assume that my form program would translate the input into a text file which I would then read

dear experts, I reproduced an experiment (questionnaire) some times. The result of the experiment is a vector of 5 factors, say (A,B,C,D,E). In the original article the result is given in 5 pairs of mean and stDev for A .. E, e.g. mean_A=37.4 and sd_A=8.1. The interval for A,B,C,D,E values is 0..50. The original data frame is not available. For a comparison of my results

Hello dear R people, for my MSc thesis I need to program some functions, and some of them simply do not work. In the following example, I made sure both vectors have the same length (10), but R gives me the following error: Error in if (vector1[i] == vector2[j]) { : missing value where TRUE/FALSE needed I googled for possible solutions, but I did not find a good explanation for this...

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.

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.

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
