Re: [R] Reformatting output of Forecasts generated by mlp model

The printed output you have shown is meaningless (and maybe mangled, since you posted in HTML): it is the result of a call to a print method for the forecast object. You need to examine that object (e.g. via str()) and/or the print method to see how to extract the data you want in whatever form

Re: [R] test of independence

The basic test of independence for a table based on the Chi-squared distribution can be done using the `chisq.test` function. This is in the stats package which is installed and loaded by default, so you don't need to do anything additional. There is also the `fisher.test` function for Fisher's

Re: [R] Problem with system() and source on linux

Read the man page for bash... source is built-in to the shell interpreter. You should invoke a single shell instance that first sources the profile and then executes the program... but this has nothing to do with R... this would be true for any program invoking an external program on a

Re: [R] Problem with system() and source on linux

Isn't 'source' a csh (tcsh, etc.) command? The sh (bash, etc.) command is a period, but you probably will need to use sh constructs in the file (like VAR=value;exportVAR) instead of csh constructs (like setenv VAR value). Bill Dunlap TIBCO Software wdunlap tibco.com On Thu, Dec 20, 2018 at

Re: [R] Problem with system() and source on linux

Hi, I can tell you what the problem is: You're probably running bash at the terminal command line, as I am: [sarahg@localhost]$ echo $0 bash but the R system function uses sh system("echo $0") sh The bash shell has a source command; the sh shell doesn't. See here for a possible solution:

[R] Reformatting output of Forecasts generated by mlp model

Dear friends, Hope you are doing great. I am using the multiple layer perceptron model (provided in R´s mlp() function for time series forecasting, but I don´t know how to reformat the output forecasts generated. mydata <- dput(datframe$Transits) > dput(datframe$Transits) c(77L, 75L, 85L, 74L,

[R] Problem with system() and source on linux

Hi! I quite often use system() to run other programs from within R, but have just hitted a problem: For a given program, I need to set up its environment, which I normally do with source /home/alobo/OTB-6.6.0-Linux64/otbenv.profile from the terminal. Now, when I try to do the same from within R,

Re: [R] extract hyperplan from e1071 model

Hi, Please don't forget to copy R-help on your reply - other people are likely to have more insight. My understanding is that you want to replicate the shaded polygons produced by plot.svm on your own plot. That's why I suggested you first try add=TRUE, and if that doesn't work, then look at the

Re: [R] extract hyperplan from e1071 model

Hi, According to the help for svm, which you probably should have started with, SV contains the support vectors, and index contains the position of the support vectors in the data matrix. As for plotting, plot.svm lets you pass additional options to plot so that you can customize the plot to

[R] extract hyperplan from e1071 model

Dear all, I am using the package e1071 for modeling SVM. I obtain a model from the data and I can plot the results; the plot shows the support vectors (as 'X's) and the shaded areas as it should be. However, I don't like the plot generated from the model and I would like instead to have more
