Hi All,
I use connections to open and close data folders needed by my package. After
each function closes I get the following warnings (depending on the connection
that has been opened).
10: closing unused connection 3
(/Library/Frameworks/R.framework/Versions/3.2/Resources/library/BondLab/BondData/bondlabMBS4.rds)
Below is the connection function that is related to the above warning:
#------------------------------------------------------------------------------------
#' A connection function to BondData calling MBS cusps
#'
#' Opens a connection to the BondData folder to call MBS cusip data
#' @param MBS.id A character string the MBS.id or cusip number current MBS.id
is supported
#' @export
MBS <- function(MBS.id = "character"){
MBS.Conn <- gzfile(description = paste(system.file(package =
"BondLab"),
"/BondData/", MBS.id, ".rds", sep = ""), open =
"rb")
MBS <- readRDS(MBS.Conn)
return(MBS)
close.connection(MBS.Conn)
}
I have googled this warning and it seems to be triggered when a function
terminates and the connection is open. But, I think the connection function
closes the connection once the object is returned. What am I doing wrong?
