A trivial question about exporting graphs in eps format. I am using a basic function to plot some data, where the input parameter is a vector y1: x <- c(1:length(y1)) matplot(x, y1, type ="n") lines(
My timeseries of daily data is composed by a dataframe of two columns; in the first column the date is dd/mm/yyyy, which in my case is not defined as dates but as character; in the second column ther
Thanks to David James, Sundar Dorai-Raj, Eric Zivot and Patrick Burns for their comments and hints. In particular Patrick Burns’ suggestion is straighforward and effective, exactly what I needed: day
Dear Splus users, this small problem made me waste a huge amount of time. Time to ask you some help. I am dealing with daily time series where the date is on the form mm/dd/yyyy I want to treat the d
Dear Splus users, I am dealing with a daily timeseries. This is a dataframe formed by two columns; in the first column there is the date (dd/mm/yyyy), in the second there is the data. This time serie
Dear Splus users, Sorry for the delay of my summary about a code involving unpaste. Many thanks to Matt Calder, James Holtman, Tom Burr, Nick Ellis, David L Lorenz and Michael Camilleri. All of you g
Thanks to Gérald Jean, Paul H. Lasky and Spencer Graves; given the integer k, the command for the binomial coefficients is choose(k, 0:k) Mark, I simply needed the numerical values, not the symboli
I need a trivial confirm: given a Gamma distribution with shape = alpha and rate = beta I need to evaluate the p_th percentile. For the 10th percentile of a Gamma(12.51, 1.41), for example, it would
Thanks to Orestis Papasouliotis, Spencer Graves and David Maxwell who helped me in managing correctly the percentiles of a Gamma distribution. The right command is qgamma. Thank you Stefano
Dear SPlus users, I am dealing with some research in time series. At this stage I need to use two tests; this is my first time, I have never used tests before. Altough I have got a lot of references
Trivial issue, but I have already wasted enough time. Within a function be myvector a vector of mode numeric and mymatrix a 2 by n matrix of mode numeric where the first row of mymatrix is seq(-0.2,
Sorry for the delay of my summary. The original question was: Within a function be myvector a vector of mode numeric and mymatrix a 2 by n matrix of mode numeric where the first row of mymatrix is se
Few weeks ago I was asking how to calculate the skewness of experimental Thanks to Richard Pugh who gave me the predefined functions of kurtosis and skewness of Splus6. Here below I report the two fu
Dear Splus users, few weeks ago I posted a question about rejection sampling, and suggestions offered by Dr.Ripley have been useful. Unfortunately it is not time, yet, to post a valid summary of the
Dear Splus users, I need to evaluate the skewness of a set of data (temperature values). Is there any predefined Splus command for the skewness? I have been looking for, with no success. An easy way
