  x,
  y = NULL,
  words,
  wordfreq = rep(1, length(x)),
  xlab = "",
  ylab = "",
  yaxt = "n",
  scale = 1,
  random.y = T,
  xlim = NULL,
  ylim = NULL,
  col = c("darkred", "navyblue"),
  fixed_col = NULL,
  ...
)

if TRUE, the y position of words is random, otherwise it represents the word frequency.

xlim

Starting value of x axis

ylim

Starting value of y axis

col

A vector of colors that is passed to colorRamp to interpolate colors over x axis

fixed_col

Optionally, a vector of the exact colors given to words.

...

additional parameters passed to the plot function

nothing

Examples

x = c(-10, -5, 3, 5)
y = c(0, 2, 5, 10)
