Hello,
I have this R script
palindrome <- function(p) {
for(i in 1:floor(nchar(p)/2) ) {
r <- nchar(p) - i + 1
if ( substr(p, i, i) != substr(p, r, r) ) return(FALSE)
}
return(TRUE)
}
that I am calling from Java using the following code:
connection.serverSource("C:\\Users\\x\\Desktop\\R Script\\Palindrome.R");
the connection is of type RConnection is created as follows:
public void startConnection() {
PATH_TO_R = SystemUtils.IS_OS_UNIX ? "R" : "C:\\Program Files\\R\\R-3.6.1\\bin\\x64\\R.exe";
try {
String cmd = PATH_TO_R + " -e " + "\"library(Rserve);Rserve(port=" + 6311+ ")\"";
Runtime.getRuntime().exec(cmd);
RConnection connection = new RConnection("localhost", 6311);
} catch (IOException | RserveException e) {
e.printStackTrace();
}
}
The problem is I am having this error thrown and have no idea how to fix it:
org.rosuda.REngine.Rserve.RserveException: serverSource failed, request status: control pipe to master process is closed/broken
any help will be much appreciated!
