R help - Nov 2013 - export vector with write() introduces line breaks

Hi,

I have a long vector which I want to export as a simple ascii text file via
write(1:600, file='test.txt', sep=',')

When I open the text file with my text editor I see that the data is structured
in columns.
So it seems that line breaks are introduced.

How can I prevent this?


Thank you!

1. Read ?write carefully. Note what it says about write() writing to
columns and the link to cat().

2. Use cat() with appropriate arguments to write your file instead.

e.g.

cat(1:600, file=yourfile,fill=FALSE)

Cheers,
Bert

Hi,

I would like to set plot-options via par() and keep them for all plots that are
created thereafter.
Currently after each plot device the parameters I can set with par() are reseted
to their default value, at least on a Mac (R 3.2.1).

Is there a way to define the parameters for plotting once at the beginning and
then keep them for an entire R session?


Thank you!

Martin:

One simple approach: write your own graphics functions that are simple
wrappers to the plot functions you use that set the par() values as
you wish. You could even put them in a package that is loaded at
startup. See ?Startup

My understanding is that so long as a graphics device remains open,
new plots on it will reuse the same par() settings. See,e.g.
?plot.new.

Cheers,
Bert

The Details section of ?par starts of with:

 "Each device has its own set of graphical parameters."

(So this is not Mac-specific.)

Strictly speaking, the options you set with par() are not "reset" when
you
open a new graphics device. Rather, when a new device is opened, it is
initialized with default values of graphics parameters.

If you can find where those default values are stored (in a brief search I
did not find them), then perhaps you can change them at session startup
time.

I haven't tested this, but you might be able to make things a little more
convenient by defining a function

  mypar <- function() par( {set whatever values you want} )

Then whenever you open a new device, immediately call that function:

pdf()
mypar()
plot(x,y)
dev.off()

png()
mypar()
plot(x,y)
dev.of()

And so on.
