NOTE: This routine is not finished yet - still contains some bugs, sometimes resulting in absolute correlation values greater than unity.

### Usage

    corEOF(x,y,lsig.mask=TRUE,sig.lev=0.05,neofs=20,
                     lty=1,col="black",lwd=1)

### Arguments

`x` | An EOF.
`y` | A station series.
`lsig.mask` | Mask out values that are not statistically significant.
`sig.lev` | Level of significanse.
`neofs` | Number of modes to include.
`lty` | Contour line type.
`col` | Contour line colour.
`lwd` | Contour line width.

### Value

A map object.
