...d is to set options(error=recover) which will dump you into the browser() environment when the error occurs and you can oka around and see what the value of variables was at the point of the error. This could give you a clue about what is going on. -pd > On 22 May 2018, at 15:29 , A.C. van der Burgh <a.c.vanderburgh at erasmusmc.nl> wrote: > > Dear all, > > Currently, I am doing a research project about serum sodium levels and falling.

Dear all, Currently, I am doing a research project about serum sodium levels and falling. I am doing my analysis in R. I am performing the multiple imputation right now. I want to perform a survival analysis later, but therefore I need to specify the Nelson-Aalen estimator. My dataset is called DF1, the event indicator is Falls and the time variable is Time. The code that I use is as follows:

Hi all, I have a very general question and I think for you maybe very easy, but I am not able to solve it. I have a dataset and that dataset contains the variable Anxiolytics. This variable is coded as 0, 1, 2. The variable looks as follows: > summary(DF$Anxiolytics) 0 1 2 NA's 1102 0 20 440 You can see that the variable is coded as 0, 1, 2, but group 1

Hi again, Anyone has an idea how to debug this problem? I tried nearly everything possible, including disabling devices in the BIOS and in CLI mode. I even replaced the CD-ROM drive with another one, just in case it is faulty. The problem persists... The thing that is hanging the probing session comes after PLIP. That's where the boot process always stops... Next thing is to remove the hard

Hi all, I have a question and I do not know If I am at the right place to ask this question. But is there someone that has the formula of CKD-Epi in code in R? I have tried a lot of loops, but none of the approaches give me the right answer. Is there someone who has this formula coded? Thank you! [[alternative HTML version deleted]]

Thank you all for your help, it worked!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'd like to put a 60GB hard disk into Gateway 2000 Pentium 150 (from '96 or '97 or so I think) running FreeBSD 4.8 RELEASE. Can anybody tell me how successful this is likely to be? Will I be able to use the full capacity of the drive? I seem to recall that the trick with large hard disks and old BIOSes is to disable the drive in

Hi all, I have a question about multiple imputation within the MICE package. I want to use passive imputation for my variable called X, because it is calculated out of multiple variables, namely Y, Z. Let's give an example with BMI. I know, that if I want to use passive imputation for BMI, I can use the following command: meth["BMI"] <- "~I(weight/(height/100)^2)"
