axis in r plot

[sathya7priya]

I have a graph plotted in r.The x axis tickmarks are at 0,5,10. I need a graph with resolution of tickmarks at 0.1 interval.When i place tickmarks of 0.1 intervals using the following command   axis(1, at=seq(0,5,0.1), cex.axis=0.7, las=2)  I only get the tickmarks of 0.1 interval that are very closed placed in the graph.I need to increase the spacing between each tickmark. Please anyone help out this.

Ticks at 0.1 interval will be very closely spaced on an axis of length 5:

[1] 51

There's no way to both have ticks at 0.1 and not have ticks at 0.1,
which is what you seem to be asking.

Why do you need that many ticks? Can you place them at .5 instead? Or larger?

Otherwise I suppose you could just make a bigger graph. You don't
provide reproducible (or any) code, so I have no idea what graphics
device you're using and can't provide specifics.

Perhaps you meant ... at=seq(0,5,1) ?

Hi sathya7priya,
I'm going to try mind reading again, so here is a possible solution.

plot(1:5,xaxt="n")
axis(1,at=seq(0,5,by=0.1),labels=rep("",51))
axis(1,at=1:5)

Jim

I need to increase the size of the graph by increasing the spacing between each tickmarks.

[sathya7priya]

I have the graph plotted with x axis(-50 to 250) and y axis (-50 to 500).I need the x axis values(-50 to 250) with spacing between two  tick marks as 1or 0.1.The graph should be wider to get enough resolution.

For the first case you shall have some special display as you will need at
least 15000 pixels wide screen.

> length(seq(-50,250,.1))
[1] 3001

I assume 4-5 pixels between ticks as minimum spacing.

For the second case it is slightly better, however still your screen
resolution shall be at least somewhere near 2000 pixels.
> length(seq(-50,250,1))
[1] 301

According to Wikipedia 27-30 inch HD display can probably cope with your
request.

Regards
Petr
