Hi all,
I'm trying to plot an svm model and I'm the following error:
plot(model, data= dados[,-1], formula=formula(dados[,2]~dados[,3]),svSymbol =
1, dataSymbol = 2, symbolPalette = rainbow(4),color.palette = terrain.colors)
Error in terms.default(x) : no terms component
Anyone knows how to
Hi all,
I don't know how to choose the formula to use when plotting an svm model, I
think I'm using the wrong one and so that is why I'm having trouble. I should
be very grateful if someone could help me on this..
dados-read.table(b.txt,sep=,nrows=3)
Hi all,
Sorry to be bothering again with probably an easy error to fix, but I've been
trying to solve the problem and haven't been able yet to do it. So I'm doing
this:
dados-read.table(b.txt,sep=,nrows=3)

Hi all,
I'm having this error, since I'm working with a data matrix I don't understand
what's happening; I've tried several ways to solve this, even working with
sparse matrix, but nothing seems to solve it, I've also tried svm (with a
simple matrix 3*3 and still got the same error.
Hi all,
I'm working with some data with 54 variables, 44 of them are binary, and I'm
using SVM in package e1071 to carry out general classification but I don't know
how to choose the best kernel for my data. I would be very grateful if someone
could help me on this task.
Best regards,

Hi all,
I'm working with some data: 54 variables and a column of classes, each
observation as one of a possible seven different classes:

Hi all,
Can anyone clear my doubts about what conclusions to take with the following
outputs of some time series tests:
adf.test(melbmax)
Augmented Dickey-Fuller Test
data: melbmax
Dickey-Fuller = -5.4075, Lag order = 15, p-value = 0.01
alternative hypothesis: stationary

Hi all,
Since I was having several problems trying to work with a large matrix I
started to use the package R.huge but I'm having the following problem
x-FileByteMatrix(covtype.data,nrow=581012,ncol=55)
Error: cannot allocate vector of size 770.8 Mb
In addition: Warning messages:

Hi,
I'm doing kolmogorv-smirnov test but I don't know what conclusions to take, I
want to know if my data has a normal distribution:
ks.test(dados1,pnorm)
One-sample Kolmogorov-Smirnov test
data: dados1
D = 0.972, p-value 2.2e-16
alternative hypothesis: two-sided

Hi,
I'm working with a numeric matrix with 55columns and 581012 rows and I'm having
problems in allocation of memory using some of the functions in R: for example
lda, rda (library MASS), princomp(package mva) and mvnorm.etest (energy
package). I've read tips to use less memory in
Hi,
I would like to know if there is any algorithm in R for transforming Binary
data sets. I want something like taking all the zeros and giving them some
negative value, for example -5, and taking all ones and giving them some
positive value, if it had been given -5 for zeros it would be 5
Hi,
I would like to know if there is an algorithm in R for testing if a data set as
a normal destribution.
Thank you for your time,
