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'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, 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, 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>

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

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

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, 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>

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>

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 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) #

Hello, I am using the package gamlss in R to plot repeated measurements. The command I am using is par.plot(). It works great except one thing about the label of the axises. I tried to label both x and y axises using ylab and xlab options. But the plot only gives variable variables. The labels did not show up. Below is the code I used. Any comments are appreciated! Thanks. library(gamlss)

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... {

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

Hello, As I mentioned in the previous message we are developing solution for wholesale companies to analyze their sales transactions by associative rules. I would very much appreciated if the community could give us some hint of what is a typical PC configuration of a professional statist (processor, RAM, HDD...)? Thanks a lot in advance and I highly appreciate your feedback! Kind regards,

Dear All, I'd like to be able to have R store (in a list component) a compressed data set, and then write it out uncompressed. gzcon and gzfile work in exactly the opposite direction. What would be a good way to handle this? Details: ---------- We have a package that uses C; part of the C output is a large sparse matrix. This is never manipulated directly by R, but always by the C code.
