multiply for vector in R
Dear All,
Is there a conmand to calculate the multiplication of the elements in a vector? For example:
a=c(1,2,3,4)
I want to get 1*2*3*4=24.
Because the dimension of the vector is high, I want to know there is a command for this task in R?
Thank you so much!
Kang

Unable to connect qemu:///system on CentOS 6.2 X86_64
...t-manager
then I started the libvirtd as follow:
/etc/init.d/lbvirtd start
So , it ran well.
However, after a few days , when I ran the command "virt-manager" , it
showed as in the attachment.
it seemed that ti cannot connect the hipervisor.
Then I did a little test:
I ran the conmand "virsh list" , but it didnot work,either.
Then I used Python as follows:
import libvirt
cc = libvirt.open(r'qemu:///system'
)
but it didnot work,either.
All the test above are under root . I hope that someone can give me some
suggestiion. Thanks to all!
