similar to: re sultant column names from reshape::cast, with a fun.aggregate vector

according to the documentation of the cast function in the reshape function, I would expect this bit of code from the examples to calculate marginal means over only the 'diet' variable. #Chick weight example names(ChickWeight) <- tolower(names(ChickWeight)) chick_m <- melt(ChickWeight, id=2:4, na.rm=TRUE) cast(chick_m, diet + chick ~ time, mean, margins="diet") But,

I'm running into some problems with the spacing of some faceted ggplot plots. I have a number of time series faceted to be one above another, but the scale labels of the y axes all clobber each other at the bottom/top of each. for example, try: qplot(x, y, data = data.frame(x = 1:10, y = 1:10, size = 1:10), facets = size ~ ., size = size) + scale_x_continuous(breaks = 1:10) +

Dear all, With normal plotting, one can size a set of points in a plot using a vector argument to cex in the points() function. This works whether you are using one of the standard R symbols (i.e. 19+) or some ascii symbol, such as '/' eg: plot(1:10, 1:10, type='n'); points(1:10, 1:10, cex = 1:10, pch = '/') Trying to make the transition to ggplot2, I find that the

Hi all, I am generally quite fond of the unix commandline keystrokes (e.g. searching back in your history with [CTRL]-R, and cutting/pasting with [CTRL]-K/Y) which work in the R commandline in *nix. Does anyone know if there's any way to get similar functionality in the Windows RGUI? I know that as of now, [CTRL]-A and -E do the same as unix (beginning and end of line) and [CTRL]-Y does a

Hi, I just wanted to know if anyone else is encountering error when compiling Evolution on FreeBSD 4.8 or 4.9. I have problems compiling e- util section of this port.

Hello all, Have some time series data stored in a data.frame, and am plotting it with ggplot2 (which is totally awesome). I have explored the documentation and mailing list archives, and I can't see any way to plot a 'smoother' that is just the K-step moving average. For example, imagine I had a data.frame called 'sleep' with 'date' as the date (from as.Date()) and

Hey all; I'm a beginner++ user of R, trying to use it to do some processing of data sets of over 1M rows, and running into a snafu. imagine that my input is a huge table of transactions, each linked to a specif user id. as I run through the transactions, I need to update a separate table for the users, but I am finding that the traditional ways of doing a table lookup are way too slow to

hey all, I feel like I must be missing something rather plain, but I don't get it. how is one supposed to use R as a PgSQL client on Windows? Assume my windows desktop is on the same network as a PgSQL server, and I just need to use R to connect and pull down some data. The thing that is confusing me is that RODBC doesn't seem to know anything about PgSQL, in that

Hi, I recently changed my motherboard to Gigabyte GA-7DPXDW+ and I can't get onboard AC97 sound to work. I added 'device pcm' to my kernel config file and sndstat returns FreeBSD Audio Driver (newpcm) Installed devices:", nothing ;( Any hints ? I'm running FreeBSD 4.8-STABLE

Hello, I have an SMP motherboard (Gigabyte GA-7DPXDW+) and I'm trying to monitor the temperature of the processor. The chipset for I/O control is Winbond W83627HF. When using any program for monitoring temperatures, I only get the temperature reading for the second processor. How do I get readings for both processors or only the first one ? TIA

Hello, I use RH Entreprise. With this version I?ve got the samaba 3.0.10-1.4E. I?ve got a problem with this version and Windows 2003 server SP1 and ArcServ. I can contact the samba share when I use the Windows Explorer. When I want to contact with ArcServ Backup software, Samba logs display this : Apr 20 10:50:34 aofrso449 smbd[29938]: api_pipe_bind_req: unknown auth type 1 requested.

Dear princely R developers to whom I owe so much of my daily productivity level, I am wondering how indexing by row and column names are implemented. That is, when I have a matrix with named rows (or columns) and I then index into that matrix using the string names (rather than integers), how does R scan through the list of names in order to figure out which row/column to use? My current

Hello, I want to be 100% sure that rsync copies something from one location to another. However, I did not see an option which would make rsync retry an operation if it failed for whatever reason (network was down when rsync started, or network went down during rsync was copying something, connection timed out etc.). For example, wget has an option like --tries=number Set number of retries

Currently, LogLevel must be set to VERBOSE to see the fingerprint of an accepted key, and the default LogLevel is INFO. Since this is useful security information, I would like to propose that the 'Accepted publickey' message be modified to include the fingerprint of the accepted key. Is this a reasonable solution? Here is an example log snippet with LogLevel VERBOSE: Oct 1 15:23:24
