Execute code on OpenCPU server

ocpu_exec will execute a function/method fn on an OpenCPU server (specified by argument server), using three dots (...) to pass arguments. It is the worker of methods defined for remote_corpus, remote_subcorpus and remote_partition objects.

ocpu_exec(fn, corpus, server, restricted = FALSE, do.call = FALSE, ...)

Arguments

fn	Name of the function/method to execute on remote server (length-one character vector).
corpus	A length-one character vector, the id of the corpus to be queried.
server	The IP/URL of the remote OpenCPU server.
restricted	A logical value, whether credentials are required to access the data.
do.call	Logical, if TRUE, the function fn is passed into a call of do.call, which offers some flexibility.
...	Arguments passed into the method/function call.

Examples

if (FALSE) {
# Get polmineR version installed on remote server
ocpu_exec(
  fn = "packageVersion",
  server = Sys.getenv("OPENCPU_SERVER"),
  do.call = TRUE,
  pkg = "polmineR"
)
}
