Hi, I have created a plot using filled.contour() and have the problem that one of the axis titles and an axis label are overlapping. I have tried changing par()$mgp (with, e.g. par(mgp=c(4,1,0)) ), but this just makes the title go off the screen. I can't work out how to make the plot take up less space in the window, so I can hopefully change mgp and sort the problem. Is changing mgp the only

Hi, This may be a stupid question, but how are the "std. error" values returned by lm() calculated? For example > summary(lm) Call: lm(formula = log10(moments[2, 1:10]) ~ log10(L_vals[1:10])) Residuals: Min 1Q Median 3Q Max -0.0052534 -0.0019473 0.0006785 0.0011740 0.0059541 Coefficients: Estimate Std. Error t value

Hi, I have a large amount of data that I would like to create a histogram of and plot and do things with in R. It is pretty much impossible to read the data into R, so I have written a program to bin the data and now have a list of counts in each bin. Is it possible to somehow import this into R and use hist(), so I can, for instance, plot the probability density? I have looked at the help page

Yes, I don't know how to copy the plot on Mac and paste on to Word because you can't right click on the graph and say "copy as metafile." I'm so surprised I can't find any information about this anywhere on the Internet... -- View this message in context: http://www.nabble.com/ON-MAC%2C-how-to-copy-a-plot-on-to-Word-document--tp19354558p19354558.html Sent from the R

Hi, I just installed R, I'm work in UBUNTU and I don't have idea about how to run a r-code written in emacs into the shell. Well I am in a shell, and obviously I can run simple commands over there, Must I compile the program? if yes, How must I do that? what is the extension? I really appreciate your help -- View this message in context:

Hi all, is there a way to override the validation methods so as to avoid the div.fieldWithErrors divs from being created on the redisplayed form? Many thanks in advance, Nicky

The only call that PeriodicalUpdater will make periodically to you is the insertion call. I think of onComplete as being ''I''ve done everything I was going to do'', which for Updater is right after it''s done a single update, but for PeriodicalUpdater, it''s after it''s finished all of its updates, so you''ll only get it once for any call

Hi all, I am writing a simple shopping cart which will consist of a single class. There will be no DB table for carts so I do not want to make my Cart a model. But where do I place my Cart class so that I can access it in my controllers? I want to be able do do things like this (for instance in a shop controller): def add_to_cart @session[''cart''].add(article_id, amount)

Hi all, I just updated lighttpd from 1.4.8 to 1.4.9 and it now refuses to start with the following error: 2006-01-24 23:12:24: (mod_fastcgi.c.989) execve failed for: public/ dispatch.fcgi No such file or directory 2006-01-24 23:12:24: (mod_fastcgi.c.1015) the fastcgi-backend public/ dispatch.fcgi failed to start: 2006-01-24 23:12:24: (mod_fastcgi.c.1019) child exited with status 2

>From a quick look at the source code, it looks like onComplete is only called when the whole thing is done - in the case of Updater, right after the update, in the case of PeriodicalUpdater, right after it has been stopped. It looks like you need to pass your callback method as an ''insertion'' method in the options. This takes two parameters, the first will probably be the

Hi all, I would like to write some custom helpers like the ones available as form helpers text_field, text_area and the like. My first try was this: custom_helper(obj, meth) ''some_string'' + obj.send(meth) + ''some_other_string'' end Object and method are being passed as symbols like this: custom_helper(:person, :name) and Ruby rightfully complains that

Dear Rusers, I'd like to take the cases of cancer of the larynx in chorley(spatstat) to explain my question. I want to join the points of cancer of the larynx with the disused industrial incinerator to generate lines, and then calculate the angles of these line comparing the horizontal line? How can i get it? It seems to be difficult to get the angles Thanks a lot. -- With Kind

Hi, i am doing a statistics course and am having trouble with an exercise where i need to determine whether my success rate at something is higher than 80%. I was successful in 29 out of 60 trials, so these were the commands i entered into R: >n=60 >p.hat=29/n >p.0=0.8 >se.0=sqrt(p.0*(1-p.0)/n) >z=(p.hat-p.0)/se.0 >print(z) Which returned: [1] -6.132224 >1-pnorm(z) Which

Hello! I am using function "curve" to create a line graph. I was wondering, if it's possible to "turn off" the default tick marks and introduce those tick marks in specific locations. For example, currently in my X axis tick marks are (automatically) at 10, 11, 12, 13 but I want them to be in 5 specific locations, like 9.89, 10.34, etc. Any hint would be greatly

Hello R users, When I type d <- density(MyData$x) I obtain a density object I can plot, But I wonder if there is a way to easily compute the length of the density curve ? ( I imagine I could compute the distances between the 512 equally spaced points using their x and y, but does it exist a smarter way ?) Regards, SW

Dear All I would like to draw a picture with the density curve of a normal distribution over a histogram of a set of random numbers extracted from the same normal distribution. Is that possible? Thanks in advance, Paul

I am learning ggplot2 commands and I have figured out how to create histograms and density curves but I am not sure how to add a density curve on top of a histogram. Here are the two graphs that I created. ## Histogram t<-rnorm(500) w<-qplot(t, main="Normal Random Sample", fill=I("blue"), colour=I("black"), geom="histogram") w ##Density Curve
