assign color to subsets
'grepl' returns a logical vector; you have to use this to get your subset.
You can use:
df_tq <- subset(df, grepl("t1", Command))
df_t2 <- subset(df, grepl("t2", Command))
# if you want to also get a subset that has both, use
df_both <- subset(df, grepl("t1", Command) & grepl("t2", Command))

assign color to subsets
now after this:

I use factor to apply the subset to df but then the Command level becomes 0
df_both$Command=factor(df_both$Command)
str(df_both)

Rsync utilization every 5 seconds
Hi.
I installed the rsync and I need it to run every 5 seconds between 2 machines.
I was planning to use it in crontab, but this allows only every minute.
I couldn?t find how to do it.
Could someone explain me how to run rsync automatically every 5 seconds?

[RFC] metadata alloc fix in machines which has PAGE_SIZE > CLUSTER_SIZE
Hi Mark/Joel,
I meet with some meta allocation bugs when I implement reflink these
days. And after some investigation, I think we should have the same
problem when we have PAGE_SIZE > CLUSTER_SIZE. So I create a scenario
today in one ppc box and try. the box panic as I expected. ;)
The scenario is that: Create a file with the disk layout like this(with
bs=512, and cs=4K).

BackgrounDRb not working properly with files ?
Hey there,
I''m kinda new to BackgrounDRb but I''m facing a big problem which I
can''t seem to wrap my head around.
The short version of it is : code that works when tested inside RoR''s
console doesn''t work when executed by a BackgrounDRb worker.
So I''ve tried a lot of things, including checking that the

Read text file subsetting rows
Hi All,
Can anyone direct me to a read function in R that will allow me to only
read in rows of a text file that begin with a particular value such as
the data below. I would read the entire file in and then limit, but the
files were constructed such that the first two letters determine how
many variables are in the row (different letters mean different numbers
of columns and different

Memory usage bar plot
Hi,
I haven't tried the code yet. Is there a way to parse this data
using R and create bar plots so that each program's 'RAM used' figures are
grouped together.
So 'uuidd' bars will be together. The data will have about 50 sets. So if
there are 100 processes each will have about 50 bars.
What is the recommended way to graph these big barplots ? I am looking

Opening all files in a directory
Is there any way that R can be programmed so that it will cycle through
all files in a directory without having to define file names? The reason I ask
is because I will have about 50-100 files in a directory which will be randomly
named. ie: MIDEX, OACES-CO2, ODEN91, etc...
If not...are there any languages out there that will do this sort of things? Or is
there another method you could

Identifying records with the correct number of repeated measures
Dear list,
I have a dataset where we sampled multiple individuals either 1 or 9
times. Our measurement variable is 'Delta13C' (see below sample
dataset). I cannot figure out how to efficiently use a vector command
(preferably) or a loop to create a new vector of the names of the
individuals sampled 9 times. Note that the 'FeatherPosition' variable
will only be "P1" for

how to drop fields by name when reading in data?
I have a number of space separated files of weather data, with some
equivalent column names, and differing number of fields in each file. Some
of the files have 40 or more vars, but I only want a subset of the fields.
I can use colClasses with read.table to drop some of the fields, but only if
I know where those columns are in the first place, and they're not always in
the same place. So I

Samba4 not able to write to group writeable folder???

[PATCH 00/42] ocfs2: Add reflink file support. V1
Hi all,
So I have finally finished the v1 of reflink for ocfs2. It has some

I'd like to send it out first for review. And Tristan and I will
continue to work on the stability of the code.
