Hello everyone,

After running the following code, I obtain this error message.


> mydata <- read.table(textConnection(mystring),
+    header=TRUE, sep=",",
+    row.names="id", na.strings=" ")
> mydata
Warning message:
closing unused connection 3 (mystring)

=====

However, when I attempt to run read.table() again and immediately submit
the close() function (below), I obtain this message:

> close(mystring)
Error in UseMethod("close") :
  no applicable method for 'close' applied to an object of class "character"
 =====

How can I avoid the warning message altogether?

Thank you,

Dan
