dump(list, file = "dumpdata.R", append = FALSE, control = "all", envir = parent.frame(), evaluate = TRUE)
list | a character vector giving the names of data objects. |
file | a character string specifying the name of a file or a connection into which the objects are dumped. The default is "dumpdata.R", unless list contains only one name, in which case the file is given a name that is based on that name (for example, "x.R"). If a blank is specified (file=""), or if it is NULL, the result is output to the console. |
append | a logical flag. If TRUE, the output is appended to file. If FALSE (the default), the contents of file is overwritten (if it exists). |
control | a character vector that specifies the deparsing options. For more detail, refer to .deparseOpts. |
envir | the environment in which to search for objects. |
evaluate | This argument is not yet implemented. A logical flag. If TRUE (the default), specifies that promises are evaluated. |
