xpose4 with -99 #20

Open JoanaXu opened 3 years ago

JoanaXu commented 3 years ago

Hello, it's a new NONMEMer named Joanna. When I trying to create a plot of ETA vs Covatiates with xpose4.ranpar.vs.cov, I found the covariates with value of -99 was not shown in the plot , which were remain in the dataset(object) with xpose4.xpose.data. So, I wonder if -99 was just handled as missing when ploting in this function? And if the -99 was handled as missing, will the records with -99 will be discarded or only -99 be recognized as NA? (xpose4 version is 4.6.1) Looking forward Your comment.

I just ran into a similar issue were -99 is used as a placeholder for missing values, but luckily I had the data in another format for reference. The -99 values are actually converted to 99 when the table file is read into R.
