Wordclouds can be very useful to highlight the main topics in text.
In R, it can be built using the wordcloud package as
described below.
Note: the wordcloud2 package allows more
customizations and is extensively described
here.
Note: this online tool is a good non-programming alternative.
#Charge the wordcloud library
library(wordcloud)
#Create a list of words (Random words concerning my work)
a <- c("Cereal","WSSMV","SBCMV","Experimentation","Talk","Conference","Writing",
"Publication","Analysis","Bioinformatics","Science","Statistics","Data",
"Programming","Wheat","Virus","Genotyping","Work","Fun","Surfing","R", "R",
"Data-Viz","Python","Linux","Programming","Graph Gallery","Biologie", "Resistance",
"Computing","Data-Science","Reproductible","GitHub","Script")
#I give a frequency to each word of this list
b <- sample(seq(0,1,0.01) , length(a) , replace=TRUE)
#The package will automatically make the wordcloud ! (I add a black background)
par(bg="black")
wordcloud(a , b , col=terrain.colors(length(a) , alpha=0.9) , rot.per=0.3 )
