Save Data and Shapefiles to Various File Formats

This function provides a unified interface for saving data to various file formats supported by the rio::export function. Additionally, it supports fast binary format .qs2 via the optional qs2 package. The format is automatically detected from the file extension to simplify the saving process.

Usage

write(data, file_path, ...)

Arguments

data: The dataset to be saved
file_path: Character string specifying the path to the output file.
...: Additional arguments to be passed to the underlying write functions. These arguments are specific to the file format being saved. Please refer to the documentation of each package used for more information.

Value

No return value, called for side effects.

Examples

# Create temporary account
tmpdir <- tempfile()
dir.create(tmpdir)

# Save a CSV file
write(mtcars, file_path = file.path(tmpdir, "file.csv"))

# Save an Excel file
write(mtcars, file_path = file.path(tmpdir, "file.xlsx"))

# Save a Stata DTA file
write(mtcars, file_path = file.path(tmpdir, "file.dta"))

# Save an RDS file
# write(mtcars, file_path = file.path(tmpdir, "file.rds"))

# Save a qs2 file (requires 'qs2')

# Save an RData file
write(list(mtcars = mtcars, iris = iris),
       file_path = file.path(tmpdir, "file.RData"))

# For saving shapefiles
# make example shape data
my_shp <-  sf::st_sfc(
  sf::st_point(c(43, 23))) |>
    cbind(mtcars[1, ]) |>
    sf::st_as_sf(crs = sf::st_crs(4326))

# save a shapefile
# write(my_shp, file_path = file.path(tmpdir, "file.shp"))

# Remove the temporary directory and its contents
unlink(tmpdir, recursive = TRUE)
