Dear users, I am attempting to plot an ols() call from the Design package, by following the procedure explained by Harald Baayen in his 2008 book 'Analyzing linguistic data. A practical introduction to statistics using R', page 175-181. I've attached my data to this e-mail (I hope it's small enough that that's ok). First I paste all the commands I ran, followed by the

I am trying to use round()to force R to display a specific number of decimals, but it seems to display <=2 decimals no matter what I specify in the digits argument. As an alternative I tried signif(), but it also produces unexpected results. See example code and results below. Format() works, but then the result no longer is numeric. Am I missing something simple? I am using R 2.9.0 on Windows

I happened to see these: > round(.5, 0) [1] 0 > round(1.5, 0) [1] 2 > round(2.5, 0) [1] 2 > round(3.5, 0) [1] 4 > round(4.5, 0) [1] 4 What is the rule here? Should not round(.5, 0) = 1, round(2.5, 0) = 3 etc? Thanks and regards,

Technically, there is a round() for 'Date' objects, but it doesn't seem very useful, because it basically just fall back to the default round() method, which only takes the 'digits' argument. Here's an example: > date <- Sys.Date() > class(date) [1] "Date" We see that there are only two round() methods in addition to the implicit built-in one; >

I have the following two tables: create table teams ( id int not null auto_increment, short_name varchar(12) not null, long_name varchar(50) not null, logo varchar(20) not null, primary key (id) ); create table rounds ( id int not null auto_increment, home_team_id int not null, away_team_id int

Dear R-users with a bit of grief I had to repeat an extensive analysis because I did not suspect (and therefore did not read the documentation) that round was implemented as "for rounding off a 5, the IEC 60559 standard is expected to be used, 'go to the even digit'", resulting in round(1.5) = 2 round (2.5) = 2. As a non-mathematician I am both puzzled and intrigued by

This is a workaround, and could be the basis for a round.Date improvement: date <- Sys.Date() as.Date(round(as.POSIXct(date), "years")) as.Date(round(as.POSIXct(Sys.Date() + 180), "years")) Duncan Murdoch On 08/02/2024 12:23 p.m., Henrik Bengtsson wrote: > Technically, there is a round() for 'Date' objects, but it doesn't > seem very useful,

The only issue might be that `trunc.Date` is currently using

Hi I have the following values pActualCost = 33.00 pPaymentCost = 29.99 So this calculation should leave me with 0.01 pPaymentDifference = pActualCost - pPaymentCost however when doing this in rails, it returns 0.00999999999999801 has anyone got any suggestions to whats going wrong and how I can correct this Thanks Scott -- Posted via http://www.ruby-forum.com/.

Hi, I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even .... For example: > round(1.5)[1] 2> round(2.5)[1] 2 While i would expect that round(2.5) be 3 and not 2. Do you have any explanation for that? I really appreciate your input, Monica

Hello all. It seems that the pf() function when used with noncentral parameters can behave badly at times. I've included some examples below, but what is happening is that with some combinations of df and ncp parameters, regardless of how large the quantile gets, the same probability value is returned. Upon first glance noncentral values greater than 200 may seem large, but they are in

...there an existing function in which you can round numbers to a set of values. I know you can use 5 * round(x/5) for rounding to the nearest 5 or so, but what if the interval size is not constant. For example: ## Not run test <- rnorm(100) round(test, c(1, 5, 10, 20, 50)) so that the test is rounded to the closest value in the vector. Thanks for the help. Cheers,

Hello All, I'm attempting to compile rsync on Solaris 10 x86 to include atime support. I've managed to patch the source, and install gcc and the necessary other packages necessary to get as far as ./configure successfully (I'm afraid I'm more of a linux than a solaris guy). I'm unable to "make" the Makefile. Did some STFW'ing and have found several variations

I'm have a (minor) problem and a question. Problem: The following code creates 5 clusters of dots of different colors. However, I need the second call outside the data.frame call to get the colors to change for some reason. I assume there's an error in the data.frame() call, but I don't know what. Question: Is there is a way to cause the resulting graphic to rotate on it's
