Hi, I am new to R. I have two questions about plotting in R: 1. How to plot several lines in a figure? Suppose I have several sets of points (xi,yi), where xi and yi are equal-length vector. plot(x1,y1) will give a line connecting these points. Another plot(x2,y2) will erase what plot before and plot the new line. Can I have these lines all drawn in the same figure? 2. How to open another figure

Hi, I have some results generated in my C++ program. I 'd like to call some R functions that can test if two sample sets are from different distribution, like Kolmogorov-Smirnov and other more sophisticated Tests. I also like to draw the histograms of the two sample sets in the same plot using R. As a newbie to R, I greatly appreciate any suggestions on how to call R in C/C++ and

Hello, Here''s the context: I read a number either pure integer or float with eventually up to 12 digits after the decimal point from a YAML file. The number is injected into a FXTextField with the following code: @value_sel = FXDataTarget.new(@value.to_s) @value_value = FXTextField.new(@matrix_mem_value, 20, at value_sel, :opts =>TEXTFIELD_NORMAL|JUSTIFY_RIGHT,

Dear R users, I need a function that gets a number and returns its number of actual decimal places. For example f(3.14) should return 2, f(3.142) should return 3, f(3.1400) should also return 2 and so on. Is such function already available in R? If not, could you give me a hint how to achieve that? Many thanks in advance. -----------------------------------------------------------------

I have a data set for different time intervals. The data has three comment lines before data for each time interval. For each time interval there are 500 data points. I want to change the dataset such that I have the following format: t1 t2 t3 ................ 0.00208 0.00417 0.00625 ................. a1 a2 a3 ...................

Hi, My question might be a little general. I have a number of values to select for the complexity parameters in some classifier, e.g. the C and gamma in SVM with RBF kernel. The selection is based on which values give the smallest cross validation error. I wonder if the randomized splitting of the available dataset into folds is done only once for all those choices for the parameter values, or

Dear R users, I am trying to produce some plots in a postscript file, but I am experiencing some issues. I open the device with ----------------------------- setPS() postscript (file='gs_mcmc_dust.ps',width=5*3,height=5*3,horizontal = FALSE, paper = "special",family = "ComputerModern",encoding="TeXtext.enc")#, onefile = FALSE -----------------------------

Hello dear R users! I did not find a function which gives information about the number of digits of a value shown by R. Do you know one? I need it to solve the problem (see RFAQ 7.31)that 0.2==0.2+0.1-0.1 FALSE The solution suggested in RFAQ is to use isTRUE(all.equal(0.2,0.2+0.1-0.1)) But if I want to compare inequality: 0.2<=0.2 +0.1-0.1 TRUE but 0.2<=0.2 +0.1-0.1 FALSE bad! but in

This mailing list truly is amazing. Thank you so much for all the help! I feel a little strange asking something that "simple" again, but I wasn't able to find it in the help... Is there a way to tell R how to display numbers (double)? How many numbers after the decimal point, etc... Thanks again, folks and have a nice New Years Eve! Dax

I have a probably very naive question about the R anova/aov functions: I've found in several text books with descriptions of anova procedures that, in nested anova (specifying the model "X~A/B", B being a factor specifying treatments, and A groups of samples within each treatment), the mean square for "among treatments" is divided by the mean square "within treatment

Hi! Does anyone know hot to set number of digits to be printed in function 'paste'? Tine Mla?

I do not know if this is a bug or a case of improper documentation. The documentation for formatC() implies that the difference between the options format="f" and format="g" is that with "g", scientific format is sometimes used. There is another difference between them that is not mentioned in the documentation. drop0trailing=FALSE is ignored when format is set to

I?m in the process of preparing a package for CRAN. The package is called ?exportR? and since it really just consists of one function, I found it natural to call it ?exportR? too. The function returns a function that does the actual job, but it is set up to work in different ways, depending on the arguments given to its creator. In short: library( exportR ) exporter <- exportR( the, arguments

Hello, What is the easiest way which enables usage of decimal comma "," instead of decimal point (".") . I would like to force all RoR views to display float numbers with comma instead of decimal point and also to allow insertion of float numbers with comma in forms. Thanks in advance, Karel -- Posted via http://www.ruby-forum.com/.

Hi, I have a float that often looks like somthing like 2003.2 in my controller (1 decimal place) Is there a way to always show it to 2 decimal places eg 2003.20 ? Thanks Scott -- Posted via http://www.ruby-forum.com/.
