similar to: [PATCH] Implement getgeo for Xen virtual block device.

Dear R-ers, I am using getGEO to download expression data from the Gene Expression Omnibus. With default settings, when a file is downloaded and parsed, lots of dotted lines are printed in the terminal, like this: .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... ..........

Rusty, I currently try to make my guest boot from an virtio root device without having an external kernel. Some of the tools that I tried expect HDIO_GETGEO to work. The most interesting value is likely the geo.start value to get the offset of a partition. This value is filled by block/ioctl.c if fops->getgeo is set. This patch also fills in some standard values for heads, sectors and

some time ago i communicated the same issue to sean, and i'm very glad he has improved the package -- thanks! i'm purposefully posting to r-devel rather than to bioconductor. i think that download.file could be improved to avoid this sort of spamming output seen previously with getGEO. currently, it prints dots (when it does) in 5 10-packs per line, line after line. instead, it could

Hi, in quite a few programs i can not browse the filesystem when opening a "listbox"; to be more clear: for example when i do in winword Open and the listbox appears, and i try to open the pull down menu winword just quits(without an error message in wine). In another program like "Camel join" it quits as soon as i go up to the level of "my computer" with a message
