Hello, I'm having problems reading a shapefile with read.shape (maptools). I'm absolutely sure my file is there, but I get "no such file". The wd is ok, since read.table for example does find the file. > getwd() [1] "D:/somedirectory/R scripts" > read.table("cities.shp") Error in read.table("cities.shp") : empty beginning of file In addition:

Hello, I'm trying to find out how I can move the y axis label of a horizontal barplot further away from the axis, in order to avoid overlap between the names (which I have rotated using las=1) and the label. I have been fiddling with the graphical parameters but nothing seems to work. Maybe a graphical representation of the graphical parameters would be helpful (cf the CSS box model).

I'm trying to fit a function y=k*l^(m*x) to some data points, with reasonable starting value estimates (I think). I keep getting "singular matrix 'a' in solve". This is the code: ox <- c(-600,-300,-200,1,100,200) ir <- c(1,2.5,4,9,14,20) model <- nls(ir ~ k*l^(m*ox),start=list(k=10,l=3,m=0.004),algorithm="plinear") summary(model) plot(ox,ir) testox <-

Hi, I'm having some problems with a bubble plot (ps package). I don't want tick marks on all four sides (just two), I want to have a smaller font size, and I would like to be able to define bubble sizes shown in the legend (now it shows 0, 0, 0, 9.747 and 4265.757 which is not really convenient. Passing some of the standard plot arguments didn't help (in fact, nothing changed).

Hello, I'm trying to produce graphs automatically from data stored in database. Before saving the graphs, I would like to maximize the size of the graphs. The best would be to directly open maximized windows with x11() but up to now I failed doing it. I tried different widths and heighs but I never managed to obtain a full screen window. Is there a command to do it ? Thanks in advance, Ptit

I'm trying to do a linear discriminant analysis on a dataset of three classes ("Affinities"), using the MASS library: > data.frame2 <- na.omit(data.frame1) > > data.ld = lda(AFFINITY ~ ., data.frame2, prior = c(1,1,1)/3) Error in var(x - group.means[g, ]) : missing observations in cov/cor What does this error message mean and how can I get rid of it? Thanks! Pieter

I'm trying to find the total number of letters in a row of a data frame. Let's say I have the following data frame. f1 <- data.frame(keyword=c("I live in Denver", I live in Kansas City, MO", "Pizza is good")) The following function gives me the number of characters in each string. So for "I live in Denver", I get 1, 4, 2, and 6. However, I want to

Hi list, I have tried with all my might to get a samba3 server (Ubuntu 12.04.1 LTS) to join a Windows 2003 domain as a member server, without any luck. I have used,from memory, the official way of doing this (aka, from the samba.org website). No matter what settings I use in smb.conf, the server always joins as a domain controller. This doesn't seem to break the domain how ever. All I am

Hi, Is nchar function knowingly slow in R? I'm doing some string formatting that requires multiple call to nchar, and nchar seems to be very slow. Experiment 1, pass nchar inside sprintf, and it takes 0.7 seconds > system.time(for (i in 1:10000) + str = sprintf('0005%020d', nchar(op)) + )[3] [1] 0.7 Experiment 2, get the length of op separately using nchar, and then pass

I am trying to get a program running under wine that needs to connect to a flexlm license server. Unfortunately I get denied when authentication because the license is a 'windows' license and I am running the program from a linux platform. Is there a way to make wine authenticate as windows? I am using the 'windows version' of the program, so I am assuming that there is

Dear Shorewall list, I need to connect a firewall to various remote sites (VPN''s) at the same time, but i do not have control of any of the remote subnets and/or the given IP address: The firewall is just a client in all of the VPN''s. So, as i see it, the remote subnets (mostly rfc1918) are doomed to get into conflict when they happen to be connected at the same time. For
