similar to: 3D pie

Hi, I would like to draw a pie chart. I've already tried out the standard pie-function in the GRAPH-package. My question: is there any 'better' function or package to draw a pie chart. For example I would like to draw a 3D pie chart. Dietrich Tissen

Hi all, I have to calculate an expression using acos -function. A strange result of acos appears *1. case with error* ss <- sin(10.74*pi/180)**2 +(cos(10.74*pi/180)*cos(10.74*pi/180)*cos(0*pi/180)) ss acos(ss) [1] NaN Warning message: NaNs produced in: acos(ss) *2. case without error* ss <- sin(10.7*pi/180)**2 +(cos(10.7*pi/180)*cos(10.7*pi/180)*cos(0*pi/180)) ss acos(ss)

Hi, I have installed R1.6.2 on a Sun Sparc workstatioin 60 under Solaris 8. I' m using csh, tcsh or bash- shell. Unfortunately, it is impossible to use the "arrow-up" key on Sun's German keyboard to repeat a R command by using this key. Always following syntax error occurs: ^[[A Does anybody have a hint ?

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of

Hi, this is a problem that occurs in the presence of two libraries (limma, xlsx) and leads to a crash of R. The problematic code is the wrong application of sweep or the product ("*") function on an LIMMA MAList object. To my knowledge, limma does not define a "*" method for MAList objects. If only LIMMA is loaded but not package xlsx, the code does not crash but rather

Hi, I experience surprisingly large timing differences for the multiplication of matrices of the same dimension. An example is given below. How can this be explained? I posted the question on Stackoverflow: https://stackoverflow.com/questions/58886111/r-why-is-matrix-product-slower-when-matrix-has-very-small-values Somebody could reproduce the behavior but I did not get any useful explanations

Dear all, I just stumbled upon some behavior of the == operator which is at least somewhat inconsistent.

Dear all, I have an n x n matrix of p-values. The matrix is symmetrical, as it describes the "each against each" p values of correlation coefficients. How can I best correct the p values of the matrix? Notably, the total number of the tests performed is n(n-1)/2, since I do not test the correlation of each variable with itself. That means, I only want to correct one half of the matrix,

Thanks for the answers, I?m aware of the ?.? option, just wanted to give a very simple example. But the lapply ??' parameter use has eluded me and thanks for enlightening me. What do you mean by messing up the call stack. As far as I understand it, piping should translate into same code as deep nesting. So then I only see a tiny downside for debugging here. No loss of time/space efficiency

Hi January, I believe the root of the xlsx issue has been identified and a fix suggested by Tomas Kalibera (see https://github.com/s-u/rJava/pull/102). In a nutshell, Oracle Java on Linux modifies the stack in a way that makes it smaller and and the same time makes it impossible for R to detect this change, leading to segfaults. It is not clear to me that the same problem would occur on Mac,

Dear all, I am a happy user of R console, but I would like to see syntax coloring. I use R 2.12 in Ubuntu Linux. I have found the packages "xterm256" and "highlight", but I was not able to figure out how to use it to highlight the syntax in console output. Also, I tried several GUI interfaces, but I was not able to find something that suits me better than the default R

Dear R users, I need to add 0 in front of a series of numbers, e.g. 1->001, 19->019, Is there a fast way of doing that? Many thanks yan [[alternative HTML version deleted]]

Another example where a data.frame is compared to (here non-null, non-empty) non-atomic values in Ops.data.frame, resulting in an error message: setClass("FOOCLASS2", ???????? slots = c(M="matrix") ) ma = new("FOOCLASS2", M=matrix(rnorm(300), 30,10)) > isS4(ma) [1] TRUE > ma == data.frame(a=1:3) Error in eval(f) : dims [product 1] do not match the length

Hi Florian, just a guess, but couldn't it be that the multiplication of very small values leads to FP underflow exceptions which have to be handled by BLAS in a less efficient way than "normal" multiplications handled by SIMD instructions ?
