Read data in an R dump file to a list

Create an R list from an R dump file

read_rdump(f, keep.source = FALSE, ...)

Arguments

f

A character string providing the dump file name.

keep.source

logical: should the source formatting be retained when echoing expressions, if possible?

...

passed to source

Details

The R dump file can be read directly by R function source, which by default would read the data into the user's workspace (the global environment). This function instead read the data to a list, making it convenient to prepare data for the stan model-fitting function.

Value

A list containing all the data defined in the dump file with keys corresponding to variable names.

Examples

x <- 1; y <- 1:10; z <- array(1:10, dim = c(2,5)) 
stan_rdump(ls(pattern = '^[xyz]'), file.path(tempdir(), "xyz.Rdump"))
l <- read_rdump(file.path(tempdir(), 'xyz.Rdump'))
print(l)
#> $x
#> [1] 1
#> 
#> $y
#>  [1]  1  2  3  4  5  6  7  8  9 10
#> 
#> $z
#>      [,1] [,2] [,3] [,4] [,5]
#> [1,]    1    3    5    7    9
#> [2,]    2    4    6    8   10
