I explain better: I have this percentage z<-1/(n*365) where n=20 so z is 0,000136986
Imagine: a matrix with length(n*365) so that matrix result is resultc( 1, 1-z result previous row-z result previous row-z .... 0) If I plot this is a linear decreasing line I want to plot an upper line wich is 10% higher tan resultc on the first values and then decreasing so that last value will be 0.05. the same in the lower, a line which values are at the beggining a 10% lower and smoothly dreasing values till the last will be 5% lower. Is it posible to make thins bands exponencially with a code? 2017-06-01 20:20 GMT+02:00 Pedro páramo <percentil...@gmail.com>: > Hi all > > I want to add a band of fluctuación (exponential decreading) to a linear > deacrecing values > > Imagine: I have a matrix like c(10,9,8,7,6,5,4,3,2,1) > > The thing is I want two new lines so that the máximum value of the new > colum on the máximum is from 10% to 5% higher and the same lower for the > mínimum > > the final two matix will be something like > > c(10+0.10*10,9+0.089*9,8+0.075*8.....,1+0.05*1) > c(10-0.10*10,9-0.09*9,8-0.075*8.....,1-0.05*1) > > What I´m looking for is a function tu calculate de "values, weights" so > that including the 10% and 5% and the nunmber of decreasing values, in this > case n=10, calculates de smotth weigths. > > I don´t know if I have expalined well so thar finally putting initial > value final and periods I can find a matrix like > > g(0.1,0.89,0.79,0.075,...,0.05) > > Exists something like that? > > [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
