Examples

# NOT RUN {
x1 <- data.frame(int = sample(1e3, replace=TRUE), 
                 num = rnorm(1e3), 
                 char = randomStrings(1e3), stringsAsFactors = FALSE)
x2 <- data.frame(int = sample(1e3, replace=TRUE), 
                 num = rnorm(1e3), 
                 char = randomStrings(1e3), 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
