Loading Package Data
Loads package data using data
, but allows the user to avoid
NOTEs for a ‘non visible binding variable’ to be thrown when checking a package.
This is possible because this function returns the loaded data.
packageData( list, envir = .GlobalEnv, ..., options = NULL, stringsAsFactors = getOption("stringsAsFactors") ) ldata(list, ..., package = NULL, error = TRUE, simplify = TRUE)
list |
character vector containing the names of the data to load. |
envir |
the environment where the data should be loaded. |
... |
other arguments eventually passed to |
options |
list of R options to set before calling |
stringsAsFactors |
logical that indicates if character columns of tabular data should be converted into factors. |
package |
a character vector giving the package(s) to look
in for data sets, or By default, all packages in the search path are used, then the ‘data’ subdirectory (if present) of the current working directory. |
error |
a logical that indicates whether an error should be thrown if the requested data cannot be found. |
simplify |
logical that indicates if queries of one object only (i.e. argument |
the loaded data.
ldata
: loads a package data in the parent frame.
It is a shortcut for packageData(list, ..., envir=parent.frame())
.
## Not run: mydata <- packageData('mydata') ## Not run: # in a package' source => won't issue a NOTE myfunction function(){ mydata <- ldata('mydata') } ## End(Not run)
