similar to: [OT] Survey about FS/OS developers

Hello, My name is Frauke Lehmann and I'm writing my master thesis about the social formation of free software/open source (FS/OS) developers. A questionnaire is one part of my research - besides interviews and observations. I understand FS/OS developers as people who are writing code (obviously), but also those that write documentation, do translations, design GUIs, or people that take care

Dear Frauke, good afternoon, Could you tell me which excel function didnt work for regression analysis and what excel version where you using?

Hey everybody, it would be really appreciate if you knew the solution to the following problem. I am trying to load data from the internet into R without having to save them. However, I need to acess a different website for each dataset. So I want to alternate an element in the URL. Eventually, I want to fill a 3 dimensional matrix/array where each slice is a two-dimensional matrix from the

Hey, I have an array with the dimensions 200x6x200 and I want to save it in a textfile. I want to be able to reload the text file to get the same array again: new.array<-load(mytextfile.txt) or something similar. I was not able to figure out a way to do that with write.table without having to save 200 text files. Is there another way? Thank you! Frauke -- View this message in context:

Dear R community, I have the following problem I hoped you could help me with. My data is save in thousand of files with a weird extension containing for numbers and a z. For example *.1405z. With list.files I managed to load this data into R. It looks like this (the row numbers are not in the original file): 35 :LATEST STAGE 3.60 FT AT 730 AM CST ON 0102 36

Hi everybody, recently a member of the community pointed me to the useful predict.lm() comment. While I was toying with it, I stumbled across the following problem. I do the regression with data from five years. But I want to do a prediction with predict.lm for only one year. Thus my dataframe for predict.lm(mod, newdata=dataframe) is shorter than the orginial vector that I did the regression

Hallo, I am totally confused why Excel and R give me totally different regression results for the data below. If you know the solution, please enlighten me. In Excel I used LINEST() and Data>Data Analysis>Regression and both (fortunately) gave the same result. The coefficients were: /b0=1.16, b1=0.957, b2=0.024, R2=0.0027, adjusted R2=-0.017/ In R I used

Dear all, I am conducting a survey on open source software. This is for my academic coursework and dissertation. It will be great to have your support and participation in this survey. This survey has two separate questionnaires, focusing on the following areas: 1) OSS development (Developers or those who contribute in coding or documentation), and 2) IT/IS costs (CIOs or IT Managers).

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?

Dear RSYNC Contributors, I seek help from designers, developers, testers,defect fixers,project managers or playing any other key role in Free/Open Source software development or maintenence in carrying out a study on practices and problems of defect management in various Free/Open Source Software projects. The insights gained from the study can further help us to extract publicly accessible

Hi, thank you for taking the time and reading my question. My question is twofold: 1. I have several matrices with variables and one matrix with water levels. I want to predict the water level with the data in the other matrices. Basically, * mod<-lm(matrix1 ~ matrix2+matrix3)* ( What looks like a minus is meant to be the wiggly minus.) Of course I could dissemble the matrices and paste

Dear R-Helpers, SAS Institute just mailed out the notice below regarding a survey of people who do data mining. To help keep the survey from becoming biased toward commercial software, I thought it would be good to post it here as well.
