Hi, Quick question on reading data. I am running simulations but want to allow the user the option to define the number of simulations. How can I have R read-in user data entered from the keyboard? Is there a difference for reading in numeric and character data? For example, I am trying to write the following in R: Enter Number of Iterations? <<<the user then enters a number say Y

Hi, I have been brought back to the "R-Side" from MatLab. I have used R in graduate econometrics but only for statistics and regression (linear and nonlinear). But now I need to run general nonlinear optimization. I know about the add-in quadprog but my problem is not QP. My problem is a general nonlinear (obj funct) with linear constraints.I know about the "ms" and

Hi, I have recently started using R again (switched from MatLab) and have a question regarding programming. How can I set up a file that will run several lines of R code? For example, in Fortran and DOS this used to be done via a batch file, and in MatLab I would write the code and save it in a script file, e.g., Test.m. An example of what I am trying to do is the following:

Hi, I have a couple of quick questions regarding R. 1) I have a ".First" function that automatically loads the quadprog package into the workspace. The .First function resides in R and is only saved if I save the workspace. The exact function is as follows: .First<-function() { library(quadprog) } Is there any way that this function can be saved outside of R? That is, is there

Hi, I recently purchased a new Easton 5E UPS. I plugged the USB cable into my computer so I could use the NUT UPS tools. However every so often NUT fails to connect to the device after a boot. Looking at dmesg I see errors like this: [ 3.277075] usb 1-9: new low-speed USB device number 6 using xhci_hcd [ 3.302091] usb 1-9: device descriptor read/8, error -32 [ 3.430241] usb 1-9: device

Hi， Rich， follow your advice， I have succeeded in compiling the “libguestfs-1.26.5” my ”libguestfs-test-tool is passed “ “ libguestfs: command: run: rm libguestfs: command: run: \ -rf /tmp/libguestfs7jxKy0 ===== TEST FINISHED OK =====” But， When I run “virt-df `virsh domuuid 147`” the error show：（debug mode) “supermin helper [00000ms] host_cpu = x86_64 supermin helper [00000ms]

Thanks again, but when I run the command "sudo update-guestfs-appliance" the result is "unpacking /tmp/superminef3fb7da4d1971287149691a8361ae0d.tmp/syslinux_3%3a4.05+dfsg-6+deb8u1_amd64.deb ... unpacking /tmp/superminef3fb7da4d1971287149691a8361ae0d.tmp/sysv-rc_2.88dsf-41ubuntu6_all.deb ... unpacking

Hi, I''ve got a rather confusing problem. My linux router box has several internet uplinks of various kinds (pppoe, ippp, ethernet). These uplinks are used by a tunnel to another location. It kinda looks like this: eth0 - internet uplink eth1 - LAN tun0 - tunnel device ppp0 - another internet uplink ... Routing is setup with iproute2 in a way that pakets with a source IP from the LAN
