Hello, I am trying to plot real-time data, refreshed at varying rates averaging once per second from a TCP socket, but the display behaves inconsistently. About 50% of the time, the plots (I have 3 in a single quartz display, via par(mfrow=c(3,1)) are refreshed correctly, but the other 50% of refreshes are incomplete: sometimes only 2 plots appear and the third spot is empty, or even the first plot is incomplete, with only axes and titles drawn. There is no evident pattern as to when the refresh fails to complete or to what degree. Am I missing an explicit refresh command? Are there better suited methods in R to accomplish this? Thanks in advance, --Rafael [[alternative HTML version deleted]]
