problem with plot
Thank you for your answers.
Here are more details about the plot() function and objects I am using.
I am using the "amap" library :
> library(amap)
Here is the plot() function :
> plot
function (x, y, ...)
{
if (is.null(attr(x, "class")) && is.function(x)) {
nms <- names(list(...))
if (missing(y))
y <- {
if (!"from" %in% nms)
0
else if (!"to" %in% nms)
1
else if (!"xlim" %in% nms)
NULL
}
if ("ylab" %in% nms)
plot.function(x, y, ...)
else plot.function(x, y, ylab = paste(deparse(substitute(x)),
"(x)"), ...)
}
else UseMethod("plot")
}
<environment: namespace:graphics>
These are my objects :
> ls()
[1] "d" "h"
"d" is a dissimilarity matrix :
> str(d)
Class 'dist' atomic [1:8106351] 0.717 0.721 0.966 0.622 0.936 ...
..- attr(*, "Size")= int 4027
..- attr(*, "Labels")= chr [1:4027] "1" "2" "3" "4" ...
..- attr(*, "Diag")= logi FALSE
..- attr(*, "Upper")= logi FALSE
..- attr(*, "method")= chr "pearson"
..- attr(*, "call")= language dist(x = lf, method = "pearson")
> object.size(d)
[1] 65012860
and "h" is the cluster dendogram built from "d" ( h <- hclust(d,
"ward") ) :
> str(h)
List of 7
$ merge : int [1:4026, 1:2] -253 -983 -1671 -520 -287 -3668 -1215
-154 -2778 -3937 ...
$ height : num [1:4026] 0.00825 0.00887 0.00909 0.00931 0.00993 ...
$ order : int [1:4027] 2152 3971 3942 1580 2192 484 1587 1550
2420 3469 ...
$ labels : chr [1:4027] "1" "2" "3" "4" ...
$ method : chr "ward"
$ call : language hclust(d = d, method = "ward")
$ dist.method: chr "pearson"
- attr(*, "class")= chr "hclust"
> object.size(h)
[1] 242792
This is what the capabilities() function shows :
> capabilities()
jpeg png tcltk X11 GNOME libz http/ftp sockets
libxml fifo cledit IEEE754 bzip2 PCRE
FALSE FALSE TRUE TRUE FALSE TRUE TRUE TRUE
TRUE TRUE TRUE TRUE TRUE TRUE
And here is the plot command I am using :
>plot(h)

Edouard

And what was the plot command that resulted in a segfault? Any and every plot command you have tried? Or just some? What does the capabilities() function show? -Don At 11:49 AM +0100 3/18/05, Edouard Henrion wrote:
Dear list, I am using R.2.0.1 on a G5 biprocessor 2.5GHz with 2Go RAM (Mac OS X 10.3.8). I have some problems to use the plot function... it makes my R application crash ! By "crash" I mean that it closes the application. And when I try through the terminal it says "segmentation fault"... I've installed R from the source (I tried the compilation with gcc 3.1 and 3.3) and the result is the same. Have someone any idea about this problem ??? Thanks, Edouard
