Create wordcloud by wordcloud2.js
Description
Function for Creating wordcloud by wordcloud2.js
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)
Arguments
data |
A data frame including word and freq in each column |
size |
Font size, default is 1. The larger size means the bigger word. |
minSize |
A character string of the subtitle |
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. |
fontFamily |
Font to use. |
fontWeight |
Font weight to use, e.g. normal, bold or 600 |
color |
color of the text, keyword 'random-dark' and 'random-light' can be used. color vector is also supported in this param |
backgroundColor |
Color of the background. |
minRotation |
If the word should rotate, the minimum rotation (in rad) the text should rotate. |
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. |
shuffle |
Shuffle the points to draw so the result will be different each time for the same list and settings. |
rotateRatio |
Probability for the word to rotate. Set the number to 1 to always rotate. |
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'. |
ellipticity |
degree of "flatness" of the shape wordcloud2.js should draw. |
widgetsize |
size of the widgets |
figPath |
The path to a figure used as a mask. |
hoverFunction |
Callback to call when the cursor enters or leaves a region occupied by a word. A string of java script function. |
Examples
library(wordcloud2)
# Global variables can go here
wordcloud2(demoFreq)
wordcloud2(demoFreq, size = 2)
wordcloud2(demoFreq, size = 1,shape = 'pentagon')
wordcloud2(demoFreq, size = 1,shape = 'star')
wordcloud2(demoFreq, size = 2,
color = "random-light", backgroundColor = "grey")
wordcloud2(demoFreq, size = 2, minRotation = -pi/2, maxRotation = -pi/2)
wordcloud2(demoFreq, size = 2, minRotation = -pi/6, maxRotation = -pi/6,
rotateRatio = 1)
wordcloud2(demoFreq, size = 2, minRotation = -pi/6, maxRotation = pi/6,
rotateRatio = 0.9)
wordcloud2(demoFreqC, size = 2,
color = "random-light", backgroundColor = "grey")
wordcloud2(demoFreqC, size = 2, minRotation = -pi/6, maxRotation = -pi/6,
rotateRatio = 1)
# Color Vector
colorVec = rep(c('red', 'skyblue'), length.out=nrow(demoFreq))
wordcloud2(demoFreq, color = colorVec, fontWeight = "bold")
wordcloud2(demoFreq,
color = ifelse(demoFreq[, 2] > 20, 'red', 'skyblue'))
