Re: [R] rpad ?

We are using RPad for a teaching application here. But we had to find many things the hard way, and additionally, it did not survive the latest R release change. There is a minimal repair, but the maintainer does not answer any email any more. We did the repair and are giving a modified version to

Hello, You could try svSocket that creates a socket server where several clients can connect simultaneously. The server is restricted to local clients for obvious security reasons, but if you would like to access it though a network, you can use stunnel to transfer the data crypted with SSL.

David Thanks you for the guidance. I am looking to drive the data into the intervals. Problem now is that I have a few 0 values that are returning as NA (e.g - (0.1,0.2] (0.1,0.2] (0.1,0.2] NA (0,0.1] ) This is causing issues when I try and use the brks to inform a clorepleth map. I

I'm trying to annotate some graphics using plotmath and finding out that the code I'm using isn't bolding the greek letters - it bolds the rest (once I adjusted the numerics to characters), it's just failing on the greek characters. Any suggestions welcomed. Jim Price. Cardiome Pharma Corp.

In an elderly version of ``plotSymbols'' (now in the cwhmisc package) that I had lying around, there was the example plot(1:10,xlab=\374) which the comments said would give a u-umlaut as the x-axis label. When I execute this plot (a) I get no x-axis label at all, and (b) the
