Subject: size and coding error in plot ?

Hello R users:

I was trying to draw a boxplot?using 2 variables (rain and wind). Both of them has length 25056. So dummy is a matrix with dimension 2 x 25056. First I tried to draw a full boxplot using the following code?and gave an error

> boxplot(dummy$Rain~dummy$Wind)

Error: cannot allocate vector of size 2.8 Gb In addition: Warning messages:
1: In rep.int(boxwex, n) :
? Reached total allocation of 1535Mb: see help(memory.size) 2: In rep.int(boxwex, n) :
? Reached total allocation of 1535Mb: see help(memory.size) 3: In rep.int(boxwex, n) :
? Reached total allocation of 1535Mb: see help(memory.size) 4: In rep.int(boxwex, n) :
? Reached total allocation of 1535Mb: see help(memory.size)

and?thereafter I tried to draw boxplots at regular intervals (that means ) and that didnt work either

> boxplot(dummy$Rain~cut(dummy$Wind,(1:25)*1000), data=dummy)

Error in plot.window(xlim = xlim, ylim = ylim, log = log, yaxs = pars$yaxs) : ? need finite 'ylim' values
In addition: Warning messages:

1: In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL'
2: In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL'
3: In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL'
4: In min(x) : no non-missing arguments to min; returning Inf
5: In max(x) : no non-missing arguments to max; returning -Inf

Also I used

?boxplot(dummy$Rain~cut(dummy$Wind, breaks=seq(from=1,to=25000,by=1000)), data=dummy)

and that showing only sigle boxplot at far left corner.

What would be the right ting to do ?
