ostrapply: Helper function for read.csv.sql

In alyssafrazee/read.csv.sql: the read.csv.sql function from sqldf, minus the Tcl/tk dependency

Description

Same as the strapply or ostrapply functions in gsubfn package, but with tcltk capabilities removed.

Usage

ostrapply(X, pattern, FUN = function(x, ...) x, ignore.case = FALSE, ...,
  empty = NULL, simplify = FALSE, USE.NAMES = FALSE, combine = c)

Arguments

X	list or (atomic) vector of character strings to be used
pattern	character string containing a regular (or character string for fixed=TRUE to be matched in the given character vector.
FUN	a function, formula, character string, list or proto object to be applied to each element of X. See discussion in gsubfn.
ignore.case	If TRUE then case is ignored in the pattern argument.
...	optional arguments to gsubfn.
empty	If there is no match to a string return this value.
simplify	logical or function. If logical, should the result be simplified to a vector or matrix, as in sapply if possible? If function, that function is applied to the result with each component of the result passed as a separate argument. Typically if the form is used it will typically be specified as rbind.
USE.NAMES	logical; if TRUE and if X is character, use X as 'names' for the result unless it had names already.
combine	combine is a function applied to the components of the result of FUN. The default is "c". "list" is another common choice. The default may change to be "list" in the future.

Details

See strapply in gsubfn. In the tornado package this function should rarely be called on its own. It is an internal process of read.csv.sql, which is an internal process of makeDb.

Value

A list of character strings.
