ADNIData training part 2

Hello all,

I download "ADNIData training part 2" PDF.

http://adni.loni.usc.edu/wp-content/uploads/2012/08/slide_data_training_part2_reduced-size.pdf

I use R example code to merge ARM and DXSUM but I have an error

Error:unexpected error symbol in dxsumvars <- c("RID","Phase","VISCODE", "VISCODE2", "DXCHANGE"

I need to solve the error.

Any help will be appreciated

arm dxsum adni r symbol

Most likely it's a copy-paste error, but your code line doesn't yield an error. We cannot support arbitrary course code examples found on the internet without further context. Please refer to the authors of the packages and course materials for help.
