RDS to qs2 format

Converts a file saved in the RDS format to the qs2 format.

Usage

rds_to_qs(input_file, output_file, compress_level = 3)

Arguments

input_file

The RDS file to convert.

output_file

The qs2 file to write.

compress_level

The zstd compression level to use when writing the qs2 file. See the qs_save help file for more details on this parameter.

Value

No value is returned. The converted file is written to disk.

Details

rds_to_qs() currently supports only gzip-compressed RDS input files. Files that are uncompressed or use another compression format are rejected.

The shuffle parameter is currently not supported when converting from RDS to qs2.

Examples

qs_tmp <- tempfile(fileext = ".qs2")
rds_tmp <- tempfile(fileext = ".RDS")

x <- runif(1e6)
saveRDS(x, rds_tmp, compress = "gzip")
rds_to_qs(input_file = rds_tmp, output_file = qs_tmp)
x2 <- qs_read(qs_tmp, validate_checksum = TRUE)
stopifnot(identical(x, x2))
