All, I would like to find a simper method that I now have to find the product of all elements in a vector: #get product of vector elements: (1,2,3,4,5) vec.product <- exp(sum(log(c(1,2,3,4,5)))) I have not found a vector product function, if one has been written. Thanks, Gerard [[alternative HTML version deleted]]

I just noticed that two key pieces of information are not given by the summary() command: N and SD. we are given the N missing, but not the converse. I know these summary value can be obtained easy, but can't understand why these two pieces of information are not provided with the other info. Thanks, Gerard

All, I am trying to put a few special symbols into a string to place on a graph (e.g., >= and superscript 2). This clearly works, but does not look good: text<-c("x2", "A>=B") I tried pasting in the >= symbol, but just comes out as an =. I have tried expression() with no luck: text<-c("x2", expression(x^2)) Any help appreciated. Thanks,

That's certainly on the list of options. I'm doing data gathering right now to see what options there are. I'd prefer not to rashly decide to run off in a direction only to discover this is already a Solved Problem. nomad On Thu, May 14, 2020 at 1:13 PM Bart J.

Thanks Bart. Unfortunately "The VIB module does not comply with the security recommendations imposed by VMWare. You lose VMWare support by installing this package." This pretty much rules out this option. :( We need vCenter support, as well. nomad On Thu, May 14, 2020 at 10:06 AM Bart J.

Hi R users, I have a test dataframe ("file1," shown below) for which I am trying to create a flag for the first and last ID record (equivalent to SAS first.id and last.id variables.

Hi All, I am running a scatter plot and trying to add a best fit line. I use an abline function, but get no line drawn over the points. I also get no error. I arm using V 2.10.0 on Windows 7. Here is my code, including the SAS transport file import: require (foreign) require (chron) require (Hmisc) require (lattice) clin <- sasxport.get("y:\\temp\\subset.xpt") attach(clin)

Hi All, I'm trying to label my plot axis with times (HH:MM) that correspond to a numeric index (values 0:6) for my time variable. I'd like to plot "08:00", "12:00", and so on, instead of 0 through 6. I have used the following line of code: axis(1, 0:6, labels=c("08:00", "12:00", "16:00", "20:00", "24:00",

Hi All, I have a small dataset named das (43 cases) in which I am trying to create a binary outcome (1/0) based on the following code: if (das$age>65 && das$bmi>30) {das$danger<-1} else das$danger<-0 I am setting a flag called 'danger' to 1 of the subject is over 65 and has a BMI > 30. I find that my statement evaluates the first record in the data.frame and

Hello, Is there any software project that uses R to do log file analisys? thanks gabi

Hi all, For those of you who don''t follow Thomas Fuch''s blog, know that a complete rewrite of InPlaceEditor / InPlaceCollectionEditor just made it into the trunk. You''ll find all the juicy details on Thomas'' post: http://mir.aculo.us/2007/7/17/in-place-editing-the-summer-2007-rewrite Do note that this is my rewrite, so if you find bugs etc., don''t

Is anyone using NUT to signal/control vCenter and vServer (6.x) for shutdown when batteries are getting low? Any recommendations? We've found https://4sysops.com/archives/startup-and-shutdown-a-vmware-cluster-with-powercli-and-powershell/ but I'd prefer to do this from the master (which is running CentOS 8) and not pollute it by installing PS on it. thanks, nomad -------------- next part

Dear R-users, I am having a problem with passing an argument to a function in a do.call function which itself is in a for statement. I am building a function to upload question pools to the blackboard learning environment. This function which transforms questions to XML style output should be generic and allow for any function to generate questions. Therefore I use do.call in this function.

Hello, We are currently installing Redhat v6, and came accross some weird behaviour from winbind. We are member of many groups in our AD. When we try to login with pam enabled access we get the following messages : -- cache_traverse_validate_fn: key length too large: (1534) > (1024) or cache_traverse_validate_fn: key length too large: (4138) > (1024) -- When we run winbind without cache

Hi, Here's a dead simple patch that causes tinc to run optional host-up and host-down scripts as hosts come up and go down. This allows custom host up/down functionality to run without having to know host names in advance. Please consider for future inclusion in tinc. I can provide documentation patches if this is accepted. Regards, Menno Smits NetBox Blue http://netboxblue.com/

Hi, One one server running tinc we're seeing a lot of syslog messages like the following: Old connection_t for XXXXX (xxx.xxx.xxx.xxx port 655) status 0014 still lingering, deleting... The last time these messages appeared, they referred to 2 of the 3 remote ends that this server is connected to. They appear regularly, once every minute. The VPN still works fine, but I have to restart tinc

Hi All, There are a variety of functions that can be applied to a variable (column) in a data frame: mean, min, max, sd, range, IQR, etc. I am aware of only two that work on the rows, using q1-q3 as example variables: rowMeans(cbind(q1,q2,q3),na.rm=T) #mean of multiple variables rowSums (cbind(q1,q2,q3),na.rm=T) #sum of multiple variables Can the standard column functions (listed in the

All, in the light of erratum #573 I''m wondering if we need to tweak or conditionally suppress fsincos emulation. The question is whether there is any possibility for getting the emulator to hit this instruction on AMD (as no real mode emulation ought to be taking place there), i.e. whether there are places where emulation gets continued eagerly in anticipation of the need for emulation

More specifically, about this patch: http://git.xiph.org/?p=flac.git;a=commitdiff;h=70b078cfd5f9d4b0692c33f018cac3c652b14f90 I downloaded the latest code from git (flac-70b078c), disabled all SSE optimizations in the code and compiled it (GCC 4.8.2). This patch doesn't change FLAC output. Either gcc is too smart and optimizes this new code back to the old, or this fix is MSVS-specific. Or
