Hi; I have a very basic question about reading element from dataframe T (2 dimentional) I want to extract element T[1,1] as a string. T[1,1] returns an element with "names", means header. this i cannot compare with any other list of strings. how can i fix that?

Hi; I am trying to cross compile LLVM for Android-NDK; I am using CMake as a build system; hence, i have defined CMAKE_SYSTEM_NAME variable so to turn on CMAKE_CROSSCOMPILING flag, being used by LLVM.

Hi All. I have a mysql statement that I would really really like to call from my Ruby program which goes like this: SELECT a, b, DAYOFWEEK(date_time) as DOW, HOUR(date_time) at hr, AVG(x/y) FROM records; This is possible by creating a 3-dimentional array of a, b, date_time containing x/y, and then finding averages and putting it into a 4-dimensional array of a, b, dow,

Hi, I need to do several matrix multiplications with the corresponding matrices forming two 3-dimentional arrays. To illustrate my problem, let's say I have the following 3-dimensional arrays: array1 <- array(1:30,dim=c(3,2,5)) array2 <- array(1:20,dim=c(2,2,5)) I know that I can get what I want with the following computation : result <- array(dim=c(dim(array1)[1],

Hi, Does anybody know if RAMI (Ruby Ami) is still functional? And is this still compatible with asterisk 1.8 Best Regards, Arjan Kroon Mobillion BV

Thank you for your reply, I'm still getting hard time to attach the hostdev, I couldn't make it work out of the doc. I took the address details from: # ll /sys/bus/scsi/devices/7:* lrwxrwxrwx 1 root root 0 Feb 8 12:58 /sys/bus/scsi/devices/7:0:0:0 -> ../../../devices/pci0000:00/0000:00:03.0/0000:08:00.1/host7/rport-7:0-0/target7:0:0/7:0:0:0 lrwxrwxrwx 1 root root 0 Feb 8 12:58

Dear R users I have the matrix of the centres of some clusters, e.g. 20 clusters each with 100 dimentions, so this matrix contains 20 rows * 100 columns numeric values. I have collected new data (each with 100 numeric values) and would like to keep the above 20 centres fixed/'unmoved' whilst just see how my new data fit in this grouping system, e.g. if the data is close to cluster 1

Hi, I'm trying to attach a host FC HBA to VM (NPIV). Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA. I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device. Also, when trying to attach the device manually as a live device - I get:

Art (and group), I'm doing this as a form of missing value analysis. Approximately 30% of the cases are missing data for one variable. To impute values for those cases, I'd like to match those cases that are missing the variable to all other cases and then take an average of those to infill. I realize there are many methods for imputing data. I'm not well versed on any in

Dear List, Is there any function in R to generate multivariate F distribution with given correlation/covariance matrix? Actually, I just want to generate some 2-dimentional non-normal data sets (skewed) for low (may be around 0.3 cor coeff.) negatively and also positively correlated variables ? Thanks in advance.

This should be simple but I am struggling. I like to easily switch in xyplot between a linear or logarithmic y-axis by setting a logical flag logY to False or True. This switch changes the scales argument of xyplot. I found out that the original two-dimentional data (Conc vs Time in my case) are converted to log10(Conc) if log=TRUE in scales, but it appears that functions like panel.curve need to

Hi, First my apologies for a non-working piece of code in a previous submission, I have corrected this error. I'm doing is individual based modelling of a pathogen and it's host. The way I've thought of doing this is with two dataframes, one of the pathogen and it's genes and effector genes, and one of the host and it's resistance genes. During the simulation, these things
