The goal of filenamr is to help in creating and modifying file names and paths. It also supports reading and writing EXIF metadata. It is primarily useful for the development of packages that work with file reading and writing and need some utilities to support this goal.
Installation
You can install the development version of filenamr like so:
pak::pkg_install("elipousson/filenamr")Making file names
The make_filename() function is design for creating structured file names based on a name and optional label, prefix, or postfix:
library(filenamr)
make_filename(
name = "Neighborhoods",
label = "Baltimore, MD"
)
#> [1] "baltimore_md_neighborhoods"
make_filename(
prefix = "Plot",
name = "Neighborhoods",
label = "Baltimore, MD"
)
#> [1] "plot_baltimore_md_neighborhoods"
make_filename(
prefix = "date",
name = "Neighborhoods",
label = "Baltimore, MD",
postfix = "map",
fileext = "jpeg"
)
#> [1] "2023-03-24_baltimore_md_neighborhoods_map.jpeg"You can also pass a filename with an extension or path (setting create = TRUE to create a directory if no directory already exist):
make_filename(
filename = "baltimore_neighborhoods",
path = "data",
fileext = "pdf",
create = FALSE
)
#> [1] "data/baltimore_neighborhoods.pdf"If you provide a number as part of a filename, you can use the increment parameter to create a filename where the number is replaced with a larger number:
make_filename(
filename = "plot",
postfix = "1",
increment = TRUE,
fileext = "png"
)
#> [1] "plot_2.png"
make_filename(
filename = "plot",
postfix = "1",
increment = 2,
fileext = "png"
)
#> [1] "plot_3.png"
