[R] Correspondence Analysis of Textual Data and Visualization of Correspondence Results in a 3d plot with the ‘ca’ package.
Good Evening, my aim is to perform a multiple correspondence analysis on a textual matrix by using the ?ca? package, which performs a 3d visualization of the results. Specifically, the frequency matrix contains words (rows) and variables (columns), and the contempt of each cell is the occurrence of each word for each category of the variables. Furthermore, the function mjca() of the ?ca? package requests a data frame as an object. What am I supposed to do in order to import the textual matrix as a data frame and compute mjca? What other packages or functions may be helpful in order to get a 3d visualization of the results?
