similar to: read.xport issues

Hi, I would like to see if a matching variable is an effect-modifier in a conditional logistic regression. Naturally, the matching variable can't enter directly in the model but as an interaction with terms that are in. However, I have problems in formulating the correct model the term that's already in the model is a factor. I am using treatment contrasts and the problem is that if I

Hi, I'm experiencing a strange issue while attempting to import some XPORT formatted datasets created using SAS 9.3. I 'm using R 2.2.1 with a recently downloaded version of the "foreign" package, although I don't have the version for that handy. I have been able to load some of the XPORT datasets, however when I increase to the entire dataset, I get the following error:

I installed the foreign library yesterday, and have successfully used the read.xport() function to get data from SAS. This is very helpful. SAS "date" and "datetime" variables become numeric variables, which is, of course, what they really are in SAS. Naturally, it is desirable to convert them to date/time objects in R. Looking at the documentation for the SAS transport

Hi All, is there a way of directly writing to disk file, the dataframe or list of dataframes that result from read.xport function. This function converts SAS export files to R dataframes. I would like to convert a SAS transport file to R, but the resulting R dataframes do not fit in the memory of my computer. Is there way to write the output of this fucntion to disk, perhaps using some pipe or

I get a segfault when trying to read a SAS transport file with rather long rows using read.xport from package foreign (version 0.4-7). The culprit seems to be these lines in xport_read in SASxport.c: 590 } else { 591 c = strchr(tmpchar, ' '); 592 *c = '\0'; 593

I see in the archives significant discussion about SAS, CDISC formats etc. for FDA, but no direct suggestion of adding a write.xport method to the foreign package. Are there significant barriers to doing so? [[alternative HTML version deleted]]

Hi All, In 2005, I noted that when I used read.xport function in the foreign package to import a SAS transport file (.xpt) with multiple files imbedded in it, data frames from some of the files were not created. Since then, I discovered that the information from the missing files is being read into one dataframe, but the data appear corrupted. This has been noted before by Dr. Harrell (in

I have found that data imported from SAS using read.xport() in package foreign (installed recently) does not match the original data, when the data consists of character strings that are only one character long. Here is an example. ---- SAS commands to create the data ---- options nocenter; data foo; a='a'; b='bb'; length c d $2; c='c'; d='

A colleague pointed out that the United States Food and Drug Administration (FDA) has adopted a transport format defined by SAS Institute as a standard for electronic submissions of data. As a result, this format has been openly documented. The URL for the documentation on the format is http://ftp.sas.com/techsup/download/technote/ts140.html Information on the FDA standards for

Hi All, Sorry that I didn't provide enough information. I've been trying to import SAS xport files that contain multiple files using package foreign's read.xport. I first attempted this back in 2005 and had problems. Some of files that were present in the SAS xport file weren't being created in R. I submitted my problem to the community:

I am trying to import data from a SAS XPORT file that contains 24 SAS files. When I use the "read.xport" procedure only about 16 data frames (components) are created.
