qs (version 0.27.3)

qreadm: qload

Description

Reads an object in a file serialized to disk using qsavem().

Usage

qreadm(file, env = parent.frame(), ...)
qload(file, env = parent.frame(), ...)

Value

Nothing is explicitly returned, but the function will load the saved objects into the workspace.

Arguments

file

The file name/path.

env

The environment where the data should be loaded.

...

additional arguments will be passed to qread.

Details

This function extends qread to replicate the functionality of base::load() to load multiple saved objects into your workspace. qload and qreadm are alias of the same function.

Examples

x1 <- data.frame(int = sample(1e3, replace=TRUE),
                 num = rnorm(1e3),
                 char = sample(starnames$`IAU Name`, 1e3, replace=TRUE),
                 stringsAsFactors = FALSE)
x2 <- data.frame(int = sample(1e3, replace=TRUE),
                 num = rnorm(1e3),
                 char = sample(starnames$`IAU Name`, 1e3, replace=TRUE),
                 stringsAsFactors = FALSE)
myfile <- tempfile()
qsavem(x1, x2, file=myfile)
rm(x1, x2)
qload(myfile)
exists('x1') && exists('x2') # returns true

# qs support multithreading
qsavem(x1, x2, file=myfile, nthreads=2)
rm(x1, x2)
qload(myfile, nthreads=2)
exists('x1') && exists('x2') # returns true
