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$Wind,
breaks=seq(from=1,to=25000,by=1000)), data=dummy)
and that showing only sigle boxplot at far left corner.
What would be the right ting to do ?
If you are simply looking to create 2 side by side boxplots, one for
each variable, Rain and Wind, and your data is in a data frame called
'dummy', then you want to use:
boxplot(dummy)
The use of '$' in your code above indicates that 'dummy' is a data
frame, not a matrix.
Right now, you are trying to draw a potentially large number of
boxplots, one for each unique value of Wind, which is why the process is
running out of memory.
If that is not what you are trying to do, then you'll need to provide
more information.
