error bars for a barchart
Hi I have the following barchart to which I want to add error bars. library(lattice) barchart(Change~fTreat,groups=Process,change, auto.key=list(points=FALSE,rectangles=TRUE), panel=function(x, y,...){ panel.barchart(x,y,origin = 0,...); panel.abline(h=0,col="black",...); } ) I have tried

Help with nonlinear regressional
Dear All, I am doing experiments in live plant tissue using a laser confocal microscope. The method is called "fluorescence recovery after photo-bleaching" (FRAP) and here follows a short summary: 1. Record/ measure fluorescence intensity in a defined, round region of interest (ROI, in this case a small spot) to determine the initial intensity value before the bleaching. This

COZIGAM removed from CRAN
Hi All, Another quick question - I noticed that COZIGAM has been removed from CRAN, and that you are referred to the archive for previous versions (last updated 23 July 2012). Is this package still ok to use? Or is there an alternative which might also fit zero-inflated GAMs? Thanks, Raeanne The Scottish Association for Marine Science (SAMS) is registered in Scotland as a Company Limited by

How can I brake a label in two lines when using expression()?
I making an xyplot and the y label is too long and needs to be in two rows, but when I brake it there is a huge gap between the last text string and the expression, and I can't get rid of it. Any ideas? Data: structure(list(Temp = c(8L, 8L, 8L, 8L, 8L, 8L, 12L, 12L, 12L, 12L, 12L, 12L), CO2 = c(380L, 380L, 380L, 750L, 750L, 750L, 380L, 380L, 380L, 750L, 750L, 750L), Treat = structure(c(3L,

Negative Binomial GAMM - theta values and convergence
Hi there, My question is about the 'theta' parameter in specification of a NB GAMM. I have fit a GAM with an optimum structure of: SB.gam4<-gam(count~offset(vol_offset)+ s(Depth_m, by=StnF, bs="cs")+StageF*RegionF, family=negbin(1, link=log), data=Zoop_2011[Zoop_2011$SpeciesF=='SB',]) However, this GAM shows heterogeneity in the

lattice: loess smooths based on y-axis values
Hi there, I'm using the lattice package to create an xy plot of abundance vs. depth for 5 stages of barnacle larvae from 5 species. Each panel of the plot represents a different stage, while different loess smoothers within each panel should represent different species. However, I would like depth to be on the y-axis and abundance to be on the x-axis, because this is more intuitive as an

metaMDS with large dataset produces 'insufficient data' warning
Greetings everyone, I am running MDS on a very large dataset (12 x 25071 - 12 model runs with 25071 output values each), and also on a very much reduced version of the dataset (randomly select 1000 of the 25071 output values). I would like to look at similarities/dissimilarities between the 12 model runs. When I use metaMDS on the full dataset, I get a warning message: Warning message: In

smbclient to access limited networks?
I am new to this ML and am sorry if this question has been answered already. I have a firewall router running Linux having two Ethernet ports (i.e. access to two networks) for INTRANET and INTERNET. This firewall needs to run smbclient to access a share on a Win2K host in the INTRANET. Looking into the Linux kernel message log, I found smbclient is broadcasting NetBIOS name service queries to

NTFS ACLs
Hi.. I'm having trouble getting to grips with NTFS ACLs in samba (2.2.3a-12.3 pkg for Debian) I've set up a samba server with the usual homes and share drives &c. Windows 98 clients are no problem. But the win 2k boxes are a different kettle of things. I was puzzled as to why one user would get another user's home share mounted on H: when i could find nothing in the 2k user

[PATCH] Start the server if another user has a PID matching our stale pidfile.
If unicorn doesn''t get terminated cleanly (for example if the machine has its power interrupted) and the pid in the pidfile gets used by another process, the current unicorn code will exit and not start a server. This tiny patch fixes that behaviour. --- lib/unicorn/http_server.rb | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/lib/unicorn/http_server.rb
