file_store {drake} | R Documentation |
Show a file's encoded representation in the cache
Description
This function simply wraps literal double quotes around
the argument x
so drake
knows it is the name of a file.
Use when you are calling functions like deps_code()
: for example,
deps_code(file_store("report.md"))
. See the examples for details.
Internally, drake
wraps the names of file targets/imports
inside literal double quotes to avoid confusion between
files and generic R objects.
Usage
file_store(x)
Arguments
x |
Character string to be turned into a filename understandable by drake (i.e., a string with literal single quotes on both ends). |
Value
A single-quoted character string: i.e., a filename understandable by drake.
Examples
# Wraps the string in single quotes.
file_store("my_file.rds") # "'my_file.rds'"
## Not run:
isolate_example("contain side effects", {
if (suppressWarnings(require("knitr"))) {
load_mtcars_example() # Get the code with drake_example("mtcars").
make(my_plan) # Run the workflow to build the targets
list.files() # Should include input "report.Rmd" and output "report.md".
head(readd(small)) # You can use symbols for ordinary objects.
# But if you want to read cached info on files, use `file_store()`.
readd(file_store("report.md"), character_only = TRUE) # File fingerprint.
deps_code(file_store("report.Rmd"))
config <- drake_config(my_plan)
deps_profile(
file_store("report.Rmd"),
plan = my_plan,
character_only = TRUE
)
}
