[R] legend question

2007-02-28 Thread Emili Tortosa-Ausina 
Hi to all,

I'm sorry for posting this question, I am sure I am missing something 
important but after reading the documentation I cannot find where the 
problem is.

I want to add a legend to a figure. If I use a simple example drawn 
from the R Reference Manual such as, for instance:

x - seq(-pi, pi, len = 65)
plot(x, sin(x), type=l, col = 2)
legend(x = -3, y = .9, legend text, pch = 1, xjust = 0.5)

then everything works just fine.

However, if I use other data such as, for instance:

y-c(1960, 1965, 1970, 1975)
z-c(1, 2, 3, 4)
plot(y, z, type=l, col = 2)
legend(x = -3, y = .9, legend text, pch = 1, xjust = 0.5)

then the legend is not shown.

Any hints?

Thanks in advance,

Emili

Re: [R] dpill in KernSmooth package

2005-07-22 Thread Emili Tortosa-Ausina 
Hi Giagomo,

I think it computes the bandwith. Anyway, have you thought about using 
lokerns insteado of KernSmooth? It computes local plug-in bandwiths 
(bandwith matrices) which perform better in many instances.

Hope that helps,

Ciao

Emili

Hi,

just a quick question does dpill computes the bandwidth or
half-bandwidth? The help says bandwidth, but in the literature there is
often confusion between the bandwidth and half-bandwidth.

thanks,
Giacomo

[R] opening RDB files

2005-07-21 Thread Emili Tortosa-Ausina 
Hi all,

I've recently upgraded to R version 2.1.1 and when trying to inspect the 
contents of many packages in the library (for instance library\MASS\R) I've 
realized wordpad, or the notepad, won't open them since they have *.RDB and 
*.RDX extensions which these editors cannot recognize.

However, libraries in previous versions of R did not have these extensions 
and I could inspect the contents of each package without any trouble.

I've been searching for this thread but did not find it.

Thank you!

Emili

[R] bandwidths for bivariate density estimation

2004-10-12 Thread Emili Tortosa-Ausina 
Hi,

I am using the KernSmooth package to estimate nonparametrically bivariate 
density functions. However, it seems that the bandwidths (one for each 
co-ordinate direction) have to be selected manually. This does not apply 
for the univariate case, for which dpik (included in KernSmooth) uses 
up-to-date plug-in rules.

Does anyone know about a package, or function, which estimates bandwidths 
for the BIVARIATE case, following, for instance, the plug-in methods 
suggested by Wand and Jones?

I will appreciate your help a lot.

Thanks,

Emili

Hi,
All do also have troubles. In my case, I get the following message:

.libPaths()[1], CRAN = NULL)
package 'RWinEdt' successfully unpacked and MD5 sums checked

In addition: Warning message:

Any help would be appreciated!!!
