xpose_data
functionThe function xpose_data()
collects all model output files and table and organizes them into an R object commonly called xpdb
for xpose data base.
xpdb <- xpose_data(runno = '001')
To make full use of the functionality offered by xpose
the following NONMEM output files should be available:
.lst/.out/.res
: used to collect information on the run (template_titles
) as well as the output table names. Alternatively a model file (.mod/.ctl
) can be used but some of the information in template_titles
may not be available..ext
: used to collect final parameter estimates and residual standard error (RSE).phi
: used for the random effects and iOFV.cov
: used for the covariance matrix.cor
: used for the correlation matrix.grd
: used for the estimation gradients.shk
: used to compute random effect shrinkage template_titles
When importing the files, xpose will return messages to the console and inform of any issue encountered during the import.
xpdb <- xpose_data(runno = '001') Looking for nonmem output tables Reading: sdtab001, catab001, cotab001, patab001 [$prob no.1] Looking for nonmem output files Reading: run001.cor, run001.cov, run001.ext, run001.grd, run001.phi
These messages can be silenced with the option quiet = TRUE
.
FIRSTONLY
tablesxpose is compatible with the $TABLE FIRSTONLY
option of NONMEM. The option FIRSTONLY
only output the first record for each ID
and hence can be used to decrease the size of output tables having no time-varying columns. During tables import xpose will merge FIRSTONLY
tables with regular tables allowing seamless use of columns from FIRSTONLY
in plots.
xpose makes use of the readr which offers the advantages of 1) rapidly import big tables and 2) automatically import compressed table (e.g. sdtab001.zip) to increase storage capacity.
Coming with future releases...
xpdb
objectA typical xpdb
object contains 8 levels namely:
code
: the parsed model codesummary
: contains key information regarding the model. All the information contained in the summary can be used as part of the template_titles
.data
: contains all output and simulation tables as well as the column indexingfiles
: contains all output filesspecial
: contains post-processed datasets used by functions like vpc()
gg_theme
: an attached ggplot2 themexp_theme
: an attached xpose themeoptions
: attached global optionsAny scripts or data that you put into this service are public.
