# Scatter Plot of Words

I call "Scatter Plot of Words" in this page.
There is the graph words are used.

This graph is useful for
Principal Component Analysis,
Multi Dimensional Scaling,
Self Organizing Map
and
Trend Analysis for Many Variables.

The type of the data is the same. Name X and Y are used.
Sample file is here.

##
Power of the Scatter Plot of Words

Two dimension graph is easy to understand.

For more than the order of 1000, this graph is not so useful.
But under the order of 1000, the information of the data is visually understood.

The selection and calculation of the X and Y is depend on the skill of the analysist.

##
Software

In my daily software, R is only one to make this graph.

##
Step of R

###
Condition

It is the example.

(1) R is needed to be instoled in the computer.

(2) "maptools" is needed to be doenloaded.

(3) Make "Rtest" folder under the C drive.

(4) In the Rtest folder, the data is put. And the name of the data file is "MapData.csv". (CSV type. Comma is used as the delimiter)

(5) The range of Y is from -1 to 1.

###
R

library("maptools")

setwd("C:/Rtest")

data <- read.csv('MapData.csv', header=T, sep=",")

data.label<-data$Name

plot(data$X,data$Y,xlab="X",ylab="Y",type="n",ylim=c(-1,1))

pointLabel(x=data$X,y=data$Y,labels=data.label)
