selectively altering variable value
Hello,
I have run an eye-tracking experiment for which I now like to analyse the saccades. Participants looked from a fixation cross (ia = 5) to the target area (ia = 4) in following example of a data frame. ia = 9 stands for everything else. A saccade is indicated by saccade = 1. Sometimes the saccade just ends before the target area (see below). This is due to the parameters that determine a

*** buffer overflow detected *** accessing invalid FD in libguestfs
We have extended collectd virt plugin to extract info about disk usage from
a libvirt domain using libguestfs. In addition to my previous mail I am
attaching some more infomration about the problem.
Currently the collectd plugin works fine and retrieves the required
statistics. The problem that I face happens after certain number of cycles
(getting disk usage statistics). Collectd is terminated

density(x)
Dear experts,
when trying to estimate an kernel density function with density(x) I get the following
error message with imported data from either EXCEL or text files:
Error in density(spr) : argument must be numeric.
Other procedues such as truehist work. If I generate data within R density works fine.
Does anybody have an idea?
Yours

I am having troubles importing values written as scientific notation

The problem is, that, given a file like that:

comparing row by row in matrix
I don't know the Russell-Rao coefficient but maybe this will help:
You can compute the number of times y and x are both 1 (that's what your
function f does) by counting 1s in y*x, i.e., sum(y*x), aka t(y)%*%x.
Ordinary matrix multiplication does this row-by-column, so if M and N are
two binary matrices, M%*%t(N) will have (i,j) entry equal to the count of 1s
in common to row i of M and
