In guiastrennec/ggxpose: Diagnostics for Pharmacometric Models

Add, remove or rename variables in an xpdb

Description

mutate() adds new variables and preserves existing ones. select() keeps only the listed variables; rename() keeps all variables.

Usage

## S3 method for class 'xpose_data'
mutate(.data, ..., .problem, .source, .where)

## S3 method for class 'xpose_data'
select(.data, ..., .problem, .source, .where)

## S3 method for class 'xpose_data'
rename(.data, ..., .problem, .source, .where)

Arguments

.data	An xpose database object.
...	Name-value pairs of expressions. Use NULL to drop a variable. These arguments are automatically quoted and evaluated in the context of the data frame. They support unquoting and splicing. See the dplyr vignette("programming") for an introduction to these concepts.
.problem	The problem from which the data will be modified
.source	The source of the data in the xpdb. Can either be 'data' or an output file extension e.g. 'phi'.
.where	A vector of element names to be edited in special (e.g. .where = c('vpc_dat', 'aggr_obs') with vpc).

Examples

# Mutate columns
xpdb_ex_pk %>% 
 mutate(lnDV = log(DV), 
        sim_count = irep(ID), 
        .problem = 1) %>% 
 dv_vs_idv(aes(y = lnDV))
 
# Rename/select columns
xpdb_ex_pk %>% 
 select(ID:TAD, DV, EVID) %>% 
 rename(TSLD = TAD) %>% 
 dv_vs_idv(aes(x = TSLD))
