R code -column headings
To do that be sure to give each dimension, itself, a name when
the matrix is defined:
mat <-matrix(c(266, 359, 533, 313, 555, 504, 502, 242), nrow = 4,
dimnames = list(Region = c("Northeast", "Midwest", "South", "West"),
Type = c("Public", "Private")))
as.data.frame(as.table(mat))
addmargins(mat)

Hello,
I have been noticing that some of my column headings are missing. Can you
give me a clue as to how to
1] replace Var1 and Var 2 by Region and type ie do it right the first time
x<-matrix(c(266, 359, 533, 313, 555, 504, 502, 242),nrow=4)
rownames(x)=c( "Northeast", "Midwest", "South", "West" )
colnames(x)=c("Public", "Private")
as.data.frame(as.table(x))
2] add a column heading for region when I use addmargins(x)
addmargins(x)
#margin.table(x,1)
#margin.table(x,2)
Thank you.
Sincerely,
Mary A. Marion
