Hello R-community,
I want to generate stacked density plots in lattice. My data consist of a
numeric variable ('pid') that is measured in different individuals ('id'),
which can be divided in two types ('type') and the measurements were repeated a
different time points ('day').
I read in the Lattice book that this can be done using the 'flowViz' package,
so I tried to reproduce the example given in there and obtained an error:
library('flowViz')
data(GvHD, package='flowCore")
densityplot(Visit~'FSC-H'|Patient, data=GvHD)
Error: ' "FSC-H" ' is/are no valid parameter(s) in this frame
I am not sure if I am missing something. I was hoping to apply something
similar to my data, maybe like this?
desityplot(id~pid|type+day, data=mydata)
Thank you in advance for your help,
Judith
