text: Plot Text
.CS
text(x, y, labels, cex, col)
.PP
.AG x,y
vector of position(s) at which to plot labels. 
A time-series or structure containing `x' and `y' may also be given
for `x'.  Missing values (NAs) are allowed.
.AG labels
optional, controls labelling.
The interpretation depends on the mode of `labels'.
If it is a character vector, `labels[i]' is plotted at each point `(x[i],y[i])'.
If it is a logical vector (of the same length as `x' and `y'), the
value `i' is plotted at each `(x[i],y[i])' for which
`labels[i]' is TRUE.
If `labels' is integer or real,
`labels[i]' is encoded and plotted at `(x[i],y[i])'.
Missing values (NAs) are allowed.
Default is `seq(x)'.
.AG cex
character expansion parameter (see `par') for each text string.
May be a vector.
.AG col
color parameter (see `par') for each text string.
May be a vector.
.PP
If the lengths of `x', `y', `labels', `cex', and `col'
are not identical, the shorter vectors are reused cyclically.
.PP
The `text' function can be used after `plot(x,y,type="n")' which
draws axes and surrounding box without plotting the data.
.EX
plot(x,y,type="n")
text(x,y)  #plot i at (x[i],y[i])
