Here's another interesting problem: if you recall I have a data frame (LCvars1) that consists of about 1500 cases (rows) of data from kids who took a test of listening comprehension. The columns are their scores (1 = correct, 0 = incorrect, . = missing) on 140 test items. The items are numbered sequentially and are ordered by increasing difficulty as you go from left to right across the

I'm sure there is a more general way to ask this question but how do you use the elements of a character vector as names of objects in an expression? For example, say you have: a = c(1,3,5,7) b = c(2,4,6,8) n=c("a","b") and you want to use the names a and b in a function (e.g. sum) sum(eval(as.name(n[1])),eval(as.name(n[2]))) works but what is a simpler way to

Dear all, I have an ASCII file where records are separated by a blank. I would like to read those data; however, only the data in rows 1, 3, 5, 7, ... are important; the other lines (2,4,6,8,....) contain no useful information for me. So far I used awk/gawk to do it: gawk '{if ((FNR % 2) != 0) {print $0}}' infile.txt > outfile.txt What is the recommended way to accomplish this in R?

On a TDM2400 with 3 FXO modules, is there a way to split each line into basically being its own trunk or another way to pull off the following scenerio: PBX has 12 inbound PSTN lines 1,3,5,7 are the 714 phone number hunt group 2,4,6,8 are the 888 phone number hunt group 9-12 are fax lines Customer wants outbound calls to go out in the following order: 8,7,6,5,4,3,2,1,12,10,11,9 Kerry

Example: xxx <- data.frame(x=1:26,y=letters) xxx$x[c(2,4,6,8)] <- NA xxx$y[c(1,3,5,7)] <- NA yyy <- edit(yyy) The missing values in xxx$y appear as blanks in the spreadsheet window that appears, whereas the missing values in the numeric column "x" appear as "NA" (as I would expect). Is this a bug or a feature? cheers, Rolf Turner P.S. >

Hi everyone, We just upgraded Samba from 4.4.5 to 4.6.5 and appear to be experiencing a problem with authentication, when the RPC domain is not supplied as part of the username. I have two scenarios where this has cropped up: RADIUS authentication using ntlm_auth Apache HTTP using mod_auth_ntlm_winbind RADIUS authentication: We use the freeRADIUS 'mschap' module to provide

Is it possible to restrict the number of concurrent calls made to a SIP peer? Or maybe the number of concurrent calls made to a particular extension. This way I can avoid asterisk trying to make more voice calls to my remote SIP gateway then I have bandwidth to handle. /davidh

Hallo, All, I have a question about changing the height or scale of the y axis. When I use following two R codes, I can get two plots. Please look at the y axes, the number of indices (x1, x2, ?) on the y axis in the first plot is smaller than that in the second plot, and hence the space between any two indices in the first plot is wider than that in the second plot. As the number of indices

Here is a nasty one: (0.65.1 on linux) > plot(c(1,2,3,4),c(2,4,6,8),log="Y") Segmentation fault (core dumped) [ml at athome ml]$ Seems the bug is in errorcall(). yes, I know the syntax is wrong, but it is an easy mistake to make and it is inconvenient to lose the work space at times.
