similar to: Plotting numbers at a specified decimal length on a plot()

Hi all, I've become quite enamored of R lately, and have decided to try to teach some of its basics (reading in data, manipulation and classical stats analyses) to my fellow grad students at the University of Toronto. I sent out a mass email and have already received some positive responses. One student, however, wanted to know what differentiates the routines that R uses, from those

Hi, I want to be able to create a vector of z-scores from a vector of continuous data, conditional on a group membership vector. Say you have 20 numbers distributed normally with a mean of 50 and an sd of 10: x <- rnorm(20, 50, 10) Then you have a vector that delineates 2 groups within x: group <- sort(rep(c("A", "B"), 10)) test.data <- data.frame(cbind(x,

Hello, Let's say I've drawn a random sample (sample1.df) from a large data frame (main.df), and I want to create a second random sample (sample2.df) where the values in its ID column *are not* in the equivalent ID column in the first sample (sample1.df). How would I go about doing this? In other words: The values in sample2.df$ID *are not found* in sample1.df$ID, and both samples are

I am new to R and am running into trouble with the function plot. When I enter in the simple code: x<-1:4 y<-5:8 plot(x,y) I get a scatter plot with 4 points as expected. However, with my own data, A and B are both vectors of length ~85, each entry a decimal in [0,1]. Using the same plot(A,B) with this data, the plot function no longer gives me a simple plot with 85 points.

Hi all, In getting to know the LLVM infrastructure, I'm having a hard time finding implementation details for closures and continuations. For closures, I've read comments such as "using a struct" as an environment to hold references to free variables, linked lists to dictionaries for various scope levels, and even things like "it's just like virtual methods". I

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 mysql schema with some decimal(20,20) fields. Now, I made a rake db_schema_dump for deployment of my applications on other machines. Rails created a schema.rb with the decimal fields as float. After a rake db_schema_import the fields are just float not decimal. How can I force rails to create decimal(20,20) columns instead of float? Thx. Marc -- Posted via

Hi: I''m trying to configure Puppet on Ubuntu, and strangely I am never able to generate a certificate because my server never shows any pending certificate requests. Put differently, on the server I am running puppetmasterd and on the client I am able to connect to the server, but the client continues printing notice: Did not receive certificate warning: peer certificate

Can someone please tell me the best approach to adding support for editing MySQL decimal types in rails? I have a field in the DB that represents currency, and the view will not let save anything past the decimal place so, 10.99 becomes 10.00 automatically. Any help is appreciated. -- 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/.

Hi all: I need an instruction that can convert decimal values into floating point numbers. i.e. say I have a decimal number 1110794174 (== 42355FBE in hex ) and (== 45.3435 as a float) essentially the mantissa and exponent representation needs to be used. Is there any way of doing this in llvm? Thanks and Regards -- -- Aparna Kotha Graduate Student Electrical and Computer Engineering

Good day, All, Is there any way to maintain the number of decimal places in the type of situation below? I would like to maintain the number of decimal places in 0.667, despite the fact that its column-mates have a fourth decimal place. Thank you for your time.

When estimating values ??each determined similarly, and in which get to them by algebraic operations in some cases, are rounded with 0 decimal places and in other cases with 2 or 3 decimal places. What is happening? Thank you. -- View this message in context: http://r.789695.n4.nabble.com/Number-of-decimal-places-tp4647549.html Sent from the R help mailing list archive at Nabble.com.

Dear list members I would like to apply a vector of labels v=c("lab1","lab2","lab3") to a dataframe df=data.frame(1:3,1:3,1:3) using some kind of loop or apply function. Any ideas? Thanks Steve Powell Checked by AVG Free Edition. 17:03 [[alternative HTML version deleted]]
