Read a file based on its extension

pm_read_file.Rd

Reads a file based on its file extension. Supports multiple file formats including tabular data (CSV, TSV), serialized R objects (RDS), and R data files (RData/RData).

Usage

pm_read_file(file, ...)

Arguments

file

Character. Path to the file to read

...

Additional arguments passed to the underlying read function (e.g., header, sep, stringsAsFactors for CSV/TSV files)

Value

The contents of the file. For RData files, returns a new environment containing all objects from the file.

Details

Supported file formats:

  • CSV: Comma-separated values files (.csv) - uses read.csv()

  • TSV: Tab-separated values files (.tsv) - uses read.table() with sep = "\t"

  • Parquet: Apache Parquet files (.parquet, .pqt) - requires the arrow package

  • RDS: R serialized data files (.rds) - uses readRDS()

  • RData/RData/Rda: R data files (.rdata, .RData, .rda, .Rda) - uses load() into a new environment

For RData files, all objects are loaded into a new environment which is returned. You can access objects using env$object_name or as.list(env).

Examples

if (FALSE) { # \dontrun{
# Read a CSV file
data <- pm_read_file("data.csv")

# Read a TSV file
data <- pm_read_file("data.tsv")

# Read an RDS file
obj <- pm_read_file("data.rds")

# Read an RData file (returns environment)
env <- pm_read_file("data.RData")
my_object <- env$my_object
} # }
