Dear R-Devels,
I am writing right now my own package that makes use of 'tempfile' and there
within with 'path.package'. When I install it, I get the error: Error in
path.package("mypackage") : none of the packages are loaded. Here is the code,
I use in my package:
".defaultDBPath" <- function()
{
db.path <- tempfile(pattern = "mmstructDB",
tmpdir = file.path(path.package("mmstruct"),
"data", "databases"),
fileext = ".db")
return(db.path)
}
.mmstructBASE <- setClass("mmstructBASE",
representation("VIRTUAL",
dbName
= "character",
dbTable
= "character"),
prototype(dbName = character(),
dbTable =
character()
)
)
.mmstructDB <- setClass("mmstructDB",
representation("VIRTUAL",
conn = "SQLiteConnection"),
contains = c("mmstructBASE"),
prototype(conn = dbConnect(dbDriver("SQLite"),
.defaultDBPath()))
)
I understand the error, but I would like to have a workaround. How can I give
the path to the package I am actually installing without getting this error?
Best
Simon
