Write derived data file



Will write a dataset and an .RDS version of it to the (by default) "DerivedData" directory. The main benefit of the .RDS dataset is that functions like input_data() and output_table() can use it for rapid reading speeding up overall function.


write_derived_data(d, name, ...)



A data.frame. Data frame to be saved.


Character. Name of file (with or without extension). If not a path, will save to DerivedData directory.


Additional arguments to be passed to utils::write.csv().


If there is no "DerivedData" data directory and you are using a different structure the argument name must be a (relative) path to an existing directory where you want your NONMEM ready dataset to be stored.


No return value, called for side effects.

## requires NMproject directory structure to operate in
## Not run: 

## read a dataset that's been copie into SourceData
d <- read.csv("SourceData/orig_data.csv")

## modify it
d <- d[d$ID < 10, ]

d %>% write_derived_data("DerivedData/data.csv")

## load it again either with
d <- read_derived_data("data")

## or more commonly if it is associated with run (e.g. m1),
## you can use input_data() to load it via the nm object

d <- input_data(m1)

## End(Not run)
