R Question

I have the below plot generated in R:

Code:

`ecdf.bdel<-ecdf(bDE[,6]) #### cumulative distribution of a vector of numeric values`

curve(1-ecdf.bdel(x),col="red",xlim=r,xlab="r2",ylab="Fraction of SVs tagged") ###plotting inverse ecdf curve

the plot is as expected. However, it leaves huge white space between axis ticks and axis labels and also between axis labels and axis labs.

Could someone offer any tip to reduce the white space.

Answer Source

Insert `mgp`

parameter like this, and see if it works. Also see `mar`

parameter for margin from all the sides. You can use both together inside `par()`

function to solve your problem.

```
par(mgp=c(3,1,0),mar(5,4,4,2)+0.1)
curve(1-ecdf.bdel(x),col="red",xlab="r2",ylab="Fraction of SVs tagged")
```

The `first`

value in `mgp`

is where your `axis labels`

moves either close to or far from axis, less value means closer to axis and high value means far from axis on both the axis i.e. x and y axis.

The `second`

value in `mgp`

is where your `tick labels`

moves either close to or far from ticks, less value means closer to tick and high value means far from ticks on both the axis i.e. x and y axis.

The `third`

value in `mgp`

is where your `ticks`

moves either close to or far from axis line itself, less value means closer to axis line and high value means far from axis line on both the axis, i.e. x and y.

`mar`

is a numerical vector of the form `c(bottom, left, top, right)`

which gives the number of lines of margin to be specified on the four sides of the plot. The default is `c(5, 4, 4, 2) + 0.1`

.

Remove `xlim`

from `curve()`

function. Your graph condition

```
par(mgp=c(10,4,0),mar=c(11,11,5,5)+0.1)
curve(1-ecdf.bdel(x),col="red",xlab="r2",ylab="Fraction of SVs tagged")
```

```
par(mgp=c(3,1,0),mar=c(5,4,4,2)+0.1)
curve(1-ecdf.bdel(x),col="red",xlab="r2",ylab="Fraction of SVs tagged")
```

Example: Using `plot`

instead of curve. It is similar

First Case:

```
par(mgp=c(7,3,0),mar=c(8,8,5,5)+0.1)
plot(1:10,xlab="X Axis", ylab="Y Axis", main="My Plot")
```

Second Case

```
par(mgp=c(3,1,0),mar=c(5,4,4,2)+0.1)
plot(1:10,xlab="X Axis", ylab="Y Axis", main="My Plot")
```
