Dear R-Users, I recently gave a try to the nice package ggplot2. Everything went well until I tried to add a smoother (using lm method for instance). On the graphic device the regression line is displayed but not confidence intervals as it should be (at least on ggplot website). I tried to do the job on both MS winXP and Linux i586: same result. Did anyone encountered this problem? Did I miss

Dear R users, I would like to query a MySQL database through R. I have installed the latest required packages (RMySQL and DBI) in R (v2.3.1).

Hi All, I run function "kmeans" to cluster a matrix. But when the matrix size is big enough, it keeps saying "did not converge in 10 iterations". Could you explain what it means and if the result is wrong? And the interesting thing is sometimes this warning happens when the sample size is around 51200 x 6, sometimes it happens around 30000 x 6. Does the warning related

Dear R-users, is there a way to pass a list of patterns to the grep function? I vaguely remember something with %in% operator...

In ocfs2_block_group_clear_bits, when num_bits != bits_cleared, it just log an error message without setting EROFS. The code is below: /* * If encountered, it means we are clearing bits multiple times. While * we are handling the case, we still need to be alerted to its * occurrence. Hence, marking it as an ERROR and not NOTICE. */ if (num_bits != bits_cleared) { mlog(ML_ERROR,

hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

This patchset converts the intel iommu driver to the dma-iommu api. While converting the driver I exposed a bug in the intel i915 driver which causes a huge amount of artifacts on the screen of my laptop. You can see a picture of it here: https://github.com/pippy360/kernelPatches/blob/master/IMG_20191219_225922.jpg This issue is most likely in the i915 driver and is most likely caused by the

ops __finalise_sg Disable combining sg segments in the dma-iommu api. Combining the sg segments exposes a bug in the intel i915 driver which causes visual artifacts and the screen to freeze. This is most likely because of how the i915 handles the returned list. It probably doesn't respect the returned value specifying the number of elements in the list and instead depends on the previous

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them

Dear R users, I have a simple question on variable manipulation. Imagine I have an object "OBJ" that has "toto" as one of its variables. I would like to understand why if I do > varname <- "toto" >OBJ$varname returns no results whereas > OBJ[varname] returns the column entitled

Hi, I have a problem with errors=panic on ext3. When a panic occurs, the error event is not recorded anywhere. So after the reboot, e2fsck doesn't kick in, the file system gets mounted again and the box panics again... Patch below moves the ERRORS_PANIC test down a bit so the journal is aborted before panic() is called. Eric Signed-off-by: Eric Lammerts <eric at lammerts.org> ---

I tried calling their toll free number and toll number last week in the morning and afternoon and was handed a recording saying this number is no longer in service. The web site was up but there was no message on the site as to why the phone numbers were not working. I just called the number now and it is working. Being around the internet for a quite a long time this gives me an uneasy

Hello R people, How can I compute the mean of the "Pulse_rate" column of the data frame or matrix from the following character object called "str_got". It has 14 entries and each entry has 8 values, separated by commas. Please go thru the following R commands to know how I tried to unstring and unlist the values to form a data frame. > str_got [1]

Can someone point me to the appropriate functions for fitting multiple statistical models that are coupled to each other. The data are measurements of salinity s and temperature t at stations id and pressures at p as well as surface elevations h at stations id. The problem is, for any new station, to estimate s at all p, given t at all p and given h. If h is ignored, the for each p, there
