elegant way to check if 2 values are in 3 columns?
Dear all, I'm trying to rerun some data linkage exercises in R (they are designed to be done in SPSS, SAS or STATA) The exercise in question is to relabel the column "treat" to "1", if "yearsep" is smaller than 1988 and columns "proc1"-"proc3" contain the values 56.36 or 59.81. My pathetic solution to do this in R currently looks like

Matching Problem: Want to match to data.frame with inexact matching identifier (one identifier has to be in the range of the other).
Hello R-Community, I have the following matching problem: I have two data.frames, one with an observation every month (per company ID), and one with an observation every quarter (per company ID; note that quarter means fiscal quarter; therefore 1Q = Jan, Feb, Mar is not necessarily correct and also, a fiscal quarter is not necessarily 3 month long). For every month and company, I want to get the

How would you spec out something like the following: def a_method x = Class.new do include Enumerable end # do something here with x end describe "The Anonymous Class" do before :each do @anonymous_class = mock Class Class.stub!(:new).and_return @anonymous_class end it "should create a new anonymous class" do

regular expressions, sub
Hi, I am trying to use sub, regexpr on expressions like log(D) ~ log(N)+I(log(N)^2)+log(t) being a model specification. The aim is to produce: "ln D ~ ln N + ln^2 N + ln t" The variable names N, t may change, the number of terms too. I succeded only partially, help on regular expressions is hard to understand for me, examples on my case are rare. The help page on R-help

Invalid address error message
Hi, I ran a d-program with syscall::open:entry probe but got the following error messages sometimes: dtrace: error on enabled probe ID 1 (ID 14: syscall::open:entry): invalid address (0xff34e000) in predicate at DIF offset 76 dtrace: error on enabled probe ID 6 (ID 14: syscall::open:entry): invalid address (0xff34e000) in predicate at DIF offset 28 I don''t know how to interpret these

dtrace causing sigtrap?
Just to let people know what my big picture is, I''m trying to write a script that will let me run a program, and name a progeny of that program that I want to debug. My script should find the first occurrence of that progeny, and run it until it finishes initializing the runtime linker, but stop it before it runs any shared library startup routines. (Failing that, I''d be okay

Oracle 9 process on Sol 10 container, doing a pollsys, using high CPU
We''re running a Solaris 10 container, with an Oracle 9.2.0.4 database - every 5-10 min, an Oracle process shoots up (using 20% + CPU) and then goes down in CPU %, doing a [i]pollsys [/i](see it via dtruss). I tried using some of the trace scripts in the Dtracetoolkit to see what the process is doing, but without any luck - also tried with the following, but dtrace process goes up to 30%

dtrace and follow fork
I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests. Is there a way I can stop the child process immediately after it is started so that I can attach a pid provider to that and trace the scanf calls in it? I have tried using the "create" probe but that did not help.

putting a running app into trace mode
Suppose I have a USDT probe in Firefox and that I''m trying to catch the startup with a probe like this: proc:::exec-success /execname == "firefox-bin"/ { start = timestamp; } and stop tracing when Firefox hits this USDT probe: mozilla:::main-entry { exit(0); } How do I put the running firefox-bin into "trace mode" so that my USDT probe fires? Thanks, Joel

Dtracing scsi
A small script to see what SCSI commands are being issued by a system: http://blogs.sun.com/roller/page/chrisg?entry=scsi_d_script Still work in progress as I needs to handle larger CDBs but it is a start, since I don''t have a disk that big it is not a problem for me yet. Also getting the return scsi packet is a hack but so far I can see no alternative short of knowing about all the

DTracing GNOME startup
Hi there, I''ve been using OpenSolaris for three months now, and I''ve started to get interested about to get my hands dirty with DTrace. Since I have an strong GNOME background, I would like to use it to help GNOME developers to find performance problems. Federico Mena Quintero, one of the Novell GNOME guys is one of the people that are working on GNOME performance stuff. He

Dtrace starts very slowly on T5440
Hi all, We just got a shiny new T5440, and one of the first things I noticed (besides the insane number of hardware contexts), is that dtrace takes 30 seconds to a minute to fire up scripts with 5-6 probes, where our T5220 usually takes under a second. Shutdown is similar, though slightly faster. This is mostly annoying because it takes so long to attach that it''s hard to tell when

When does ufunc/func work?
I''m trying to profile the time spent in libc functions in a large build job (building Perl), and I have trouble getting ufunc and func working. (func() is not strictly needed; I was just hoping to use it in order to profile idle time.) Here''s the story. I''ve written a dtrace script to start a separate dtrace process for each invoked command: int fileid;

OpenSSH3.0p1/PAM/Sol8
Hi there, I just tried out OpenSSH3.0p1 running on Solaris 8 with PAM (--with-PAM). The problem was mentioned some time ago and is still there :-( When a password is expired you are prompted to change it now, enter your login password and after doing so you are instantly disconnected. I think this is a problem with PAM and not SSH, but how can I get a solution on this ? sshd is running without

Conflict between LDAP and Privilege Separation?
Hi all. OpenSSH_4.1p1, OpenSSL 0.9.7g 11 Apr 2005 on Solaris 8 using host-based authentication. With "PrivilegeSeparation yes" and "UsePAM no" everything works as desired. If I enable PAM, I am able to connect, but just before it gives me a shell, it disconnects. If I leave PAM enabled and disable PrivilegeSeparation, it works. Is this a current limitation, or is there

Using DTrace to monitor productions systems
Hi, we are developing and operating an very critical application in the financial sector. Now our customer wants us to report performance data (roundtrip times of the messages routed). My idea is using dtrace to measure the times with the pid provider catching the timestamps on entry of the in and out functions of the processes. Now my questions ;-): 1) Is this an appropriate method to monitor

Slow pkginstalls due to long door_calls to nscd
Hi all, I am installing a zone onto two different V445s running S10U4 and the zones are taking hours to install (about 1000 packages), that is, the problem is identical on both systems. A bit of trussing and dtracing has shown that the pkginstalls being run by the zoneadm install are making door_call calls to nscd that are taking very long, so far observed to be 5 to 40 seconds, but always in

X Error of failed request: BadMatch (invalid parameter attributes)

All Notes functions work, even printing. However, when I File|Exit from Notes and then try to restart it, I get an error. here is the error message: X Error of failed request: BadMatch (invalid parameter attributes) Major
