[R] How to remove the grid around the plot(ca(...)) function?

[David L Carlson]

You will have to construct it yourself using plot(), points(), and text():

> d1.ca <- ca(d1)
> d1.plt <- plot(d1.ca)

d1.ca$rowmass will contain the row masses and d1.ca$colmass the column masses
d1.ca$rownames and d1.ca$colnames, the names

d1.plt$rows has the row coordinates and d1.plt$cols, the column coordinates.

Subject: [R] How to remove the grid around the plot(ca(...)) function?

Hello R-experts,

Could anyone suggest how I can remove the grid coming out of the
plot(ca(...)) function?

For instance I have:

library(ca)
v1 <- c(10,15,20,15,25)
v2 <- c(23,4,7,12,2)
v3 <- c(10,70,2,3,7)
d1 <- data.frame(v1,v2,v3)
rownames(d1) <- c("B1","B2","B3","B4","B5")
plot(ca(d1), mass = c(TRUE,FALSE), xlab="", ylab="")

As you can I could remove the X and Y axis label, but basically I am
looking for a chart containing only the data points - with relative inertia
represented by their size - and labels with no extra lines or number, any
clue on how I can do that?

Thank you,

Luca
