Hi, i create two constants kilo and milli in [1]. These should be available after loading library(sitools) How should i export them and what have i done wrong? (Other suggestions for improving the package are welcome too) The ready to use .tar.gz and the source can be found on github [2,3] kind regatds, [1] https://github.com/jonasstein/sitools/blob/master/init.R [2]

Hi, how can i play around with my first selfwritten package [*] without to install it to my debian system? I think of something like doing this: /tmp/$ R R version 2.11.1 (2010-05-31) Copyright (C) 2010 The R Foundation for Statistical Computing ISBN 3-900051-07-0 > library(/tmp/sitools) 3 * kilo [1] 3000 [*] https://github.com/jonasstein/sitools -- Jonas Stein <news at

when i plot with the following command on console: $ R CMD BATCH cp_messung.R in the R-script i wrote x11() in the beginning, so it draws a nice plot on my screen. But sadly it disappeares after a second or two. How can i make it to wait until i press a key or something? thank you. -- kind regards, Jonas Stein <news at jonasstein.de>

Hi, i want to make my plots look uniform in LaTeX documents. - usage of the same font on axes and in legend like LaTeX uses (for example "Computer Modern") - put real LaTeX formulas on the axes Have you any hints how i can achieve that? I had no luck two years ago, but i want to try it again now. kind regards, -- Jonas Stein <news at jonasstein.de>

Hi, i want to import data from .ods and .xls files in R on a linux system. Seems it was a faq in the past, but i found only solutions for Windows. Is there a handy solution for linux? The best would be something like mytab <-read.ods(...) Any hints? Thanks a lot for reading so far, -- Jonas Stein <news at jonasstein.de>

Hi, fp is a data frame like this ,----[ fp ] | Frequenz AmpNorm | 1 3322 0.0379490639 | 2 3061 0.0476033058 | 3 2833 0.0592954124 | 4 2242 0.1275510204 `---- i want to find the "Frequenz" where "AmpNorm" is max. I use this line as workaround: PeakFreqHz = subset(fp, AmpNorm == max(AmpNorm))$Frequenz[1] Is there something nicer? And is there an

Hi, while searching for a solution i found many solutions in the internet. But the postings seemed to be many years old and the workaround was a dirty hack like this: http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-I-create-rotated-axis-labels_003f Now its the year 2009 and there might have been some improvement... Does anyone know a nice and easy way to turn labels on the y axis in the

Hi, may be its a very simple question, but i did not find any documentation about a 'include' command or something like this. I have to set many constants in my R-files and want to move all these to one file, so that i can reuse it in all other R-files. Something like include("~/R/myconstants.R") kind regards, -- Jonas Stein <news at jonasstein.de>

Hi i have a list of many files and want to load them into a list of tables, that can be adressed with a variable 'i'. something like files = c("0125um","2000um","2200um","2500um","2700um") for (i in 1:5) { fp[i] <- read.table( files[i] ) } but this does not work of course. Has anyone a good hint? Thank you, -- Jonas Stein

Hi, how can i plot two different x axis in a ggplot2 qplot? I want to plot Farenheit and Celsius in one diagram. x1:Farenheit x2:Celsius kind regards, -- Jonas Stein <news at jonasstein.de>

Why fails nls with "singular gradient" here? I post a minimal example on the bottom and would be very happy if someone could help me. Kind regards, ########### # define some constants smallc <- 0.0001 t <- seq(0,1,0.001) t0 <- 0.5 tau1 <- 0.02 # generate yy(t) yy <- 1/2 * ( 1- tanh((t - t0)/smallc) * exp(-t / tau1) ) + rnorm(length(t))*0.01 # show the curve

i have a table like this of an value and its tolerance length delta-length 12.2232 0.4 123.422 0.034123 1234 12 i want to round the value to the significant digits in this way: my-round(length,delta-length) 12.2 , 0.4 123.42 , 0.03 1234 , 12 how can i do this with R? please CC to email, thanks so far, -- Jonas Stein <news at jonasstein.de>

i'd like to plot a legend in my diagram. The diagram will be included in a TikZ LaTeX document later. I tried the legend() function, but - it can not find a good place it self where the legend fits and playing around with coordinates and scaling consumes a lot time - standard settings for the text need adjustment (linespacing is quite large and so on) Is there an alternative to

Hi, how can i adjust the font in a ggplot2 qplot so that it will look similar to the LaTeX font? Computer Modern Sans Serif in the same size would be nice. My output device is ggsave(filename="test.pdf", width=5.5, height=3, dpi=300) and i will include the graphic with 5.5 inch in LaTeX. I found some pages about that topic but all solutions that i found have been very complicate

i want to plot values with frequency on a logarithmic x axis. similar to this example that i found in the web: http://www.usspeaker.com/jensen%20p15n-graph.gif I would like to convert long numbers to si prefix notation like in the example (200000 to 200k, 35000000 to 3.5 M) Of course i could create labels by hand, but i have many files so i need some automatic function. Has anyone done that

I want to fit discrete data that was measured on a wavegenerator. In this minimal example i generate some artificial data: testsin <- 2+ 5 * sin(1:100) #generate sin data testsin <- testsin+ rnorm(length(testsin), sd = 0.01) #add noise mydata <- list(X=1:100, Y=testsin) # generate mydata object nlmod <- nls(X ~ A+B*sin(C* Y), data=mydata, start=list(A=2, B=4, C=1), trace=TRUE) #

I realize this is (mostly) off topic, but I'm befuddled as to *how* one can post to the Gmane Pan Users' group (gmane.comp.gnome.apps.pan.user) using any nntp USENET client (e.g., Pan, on Centos). I'm already subscribed (by having sent an email to pan-users at nongnu.org); but I just want that USENET group to work like *this* USENET group, where I can post using a server:port

Hi, what is actually the best method to include R-plots into LaTeX documents? At the moment i use postscript("myplot.eps", width = 12.0, height = 9.0, horizontal = FALSE, onefile = TRUE, paper = "special",encoding = "TeXtext.enc") plot(foo,bar) dev.off() But it is a bit unhandy to scale later and its difficult to get nice formula in the plots. And how should

As of the WineHQ.com move, our mail server (using qmail) reports the following error in the logs: Mar 12 13:22:01 griffin tcp-env[14557]: warning: host name/name mismatch: www.codeweavers.com != wine.codeweavers.com Mar 12 13:22:01 griffin tcp-env[14557]: refused connect from 207.1.200.18 Unfortunately, I'm not in a position to change the settings of our server, so I was hoping that this

Hi, i would like to plot a few hundred .csv files. Each file contains one curve with x,y values to plot. I have been searching for "gnu r read many files qplot" and similar words. I found for loops that use assign to generate one variable containing a dataframe. When i uesed the classic "plot' command i could add the curves with something like for... {
