Dear R-helpers, I would like to have my students read into R an online Stata dataset: 'http://www.stat.ucla.edu/projects/datasets/risk_project.dta' I was able to read it into R after downloading it and converting it with StatTransfer (http://www.stattransfer.com/). Here is what happens when I use read.dta() as I would use read.table(): > require(foreign) > risk2 <- read.dta('http://www.stat.ucla.edu/projects/datasets/ris...

Hope everyone id doing great .. Just need some clarification over the limit of write.dta. I have some coauthors that use stata and I need to send them my data in .dta format. the data.frame is 41706x229 and I get the following Error in write.dta(Panel, file = "STATADATA/Panel.dta", version = 7) : a binary write error occured Once I subset the data everything works out fin...

Thanks in advance. I pass data sets between R and Stata and think dta files would be the best files for this. To do this I can use package foreign or package memisc. I mostly use foreign, although have used memisc and this problem mostly didn't happen, but created errors at other times. I have a csv data set (and created a test case) with with at least one colum...

Hi, I am new to R and I want to export data into Stata. Could somebody help with that? Thanks a lot.
