+\usage{
+wordcloud2(data, size = 1, minSize = 0, gridSize =  0,
+    fontFamily = 'Segoe UI', fontWeight = 'bold',
+    color = 'random-dark', backgroundColor = "white",
+    minRotation = -pi/4, maxRotation = pi/4, shuffle = TRUE,
+    rotateRatio = 0.4, shape = 'circle', ellipticity = 0.65,
+    widgetsize = NULL, figPath = NULL, hoverFunction = NULL, seed = NULL)
+}
+\arguments{
+\item{data}{A data frame including word and freq in each column}
+
+\item{size}{Font size, default is 1. The larger size means the bigger word.}
+
+\item{minSize}{minimum font size to draw on the canvas.}
+
+\item{gridSize}{Size of the grid in pixels for marking the availability of the canvas
+the larger the grid size, the bigger the gap between words.}
+
+\item{fontFamily}{Font to use.}
+
+\item{fontWeight}{Font weight to use, e.g. normal, bold or 600}
+
+\item{color}{color of the text, keyword 'random-dark' and 'random-light' can be used.
+color vector is also supported in this param}
+
+\item{backgroundColor}{Color of the background.}
+
+\item{minRotation}{If the word should rotate, the minimum rotation
+(in rad) the text should rotate.}
+
+\item{maxRotation}{If the word should rotate, the maximum rotation (in rad) the text should rotate.
+Set the two value equal to keep all text in one angle.}
+
+\item{shuffle}{Shuffle the points to draw so the result will be different each time for the same list and settings.}
+
+\item{rotateRatio}{Probability for the word to rotate. Set the number to 1 to always rotate.}
+
+\item{shape}{The shape of the "cloud" to draw. Can be a keyword present. Available presents are 'circle'
+(default), 'cardioid' (apple or heart shape curve, the most known polar equation),
+'diamond' (alias of square), 'triangle-forward', 'triangle', 'pentagon', and 'star'.}
+
+\item{ellipticity}{degree of "flatness" of the shape wordcloud2.js should draw.}
+
+\item{widgetsize}{size of the widgets}
+
+\item{figPath}{The path to a figure used as a mask.}
+
+\item{hoverFunction}{Callback to call when the cursor enters or leaves a region occupied
+by a word. A string of java script function.}
+
+\item{seed}{Seed to pass to the JS library. Useful if you want a reproducible figure.}
