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

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

Details

The shuffle parameters is currently not supported when converting from RDS to qs2. When reading the resulting qs2 file, validate_checksum must be set to FALSE.

Examples

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

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