Arguments

df	A dataframe with x and y coordinates and text labels
n	the number of points you wish to move
x	the column name of the x axis coordinates
y	the column name of the y axis coordinates
l	the column name of the point labels
cols	the color vector to iterate through while assigning new positions.
...	other paramters passed on to text

  x <- rnorm(20); y <- rnorm(20)
  df <- data.frame(x,y, lab=as.character(letters[1:20]))
  plot(df$x, df$y, pch=''); text(df$x, df$y, df$lab)
  ## df <- mvlabs(df, 'x','y','lab', n=3)  
  plot(df$x, df$y, pch=''); text(df$x, df$y, df$lab)
