PXE booting UEFI
Good Afternoon,
As per the installation guide, section 30.2.2 I?ve created an efidefault file at /var/lib/tftpboot/pxelinux/pxelinux.cfg/efidefault
However, this file is never requested by the 64 bit PXE loader (bootx64.efi), as shown by tcpdump:

acf and na.pass
Hello,
I would like to have some information about acf with missing values.
Let us consider this example:
x=rnorm(100)
x2=x
x2[sample(100,10)]=NA
acf1=acf(x)
acf2=acf(x2,na.action=na.pass)
The computation of the acf is different for the two data sets. Looking
at the the code reveals that with missing values, the computation of acf
takes into account the number of pairs of non-NA values (i.e. the number
of pairs of data that are used to compute the acf, a...
