[R] Printing a list of simultaneous equations

[Sorkin, John]

I am trying to print a list of equations in an easily readable form. At this time all I can get is  a series of characters enclosed in quotation marks rather than equations with numbers and equal signs. What I get is


    y     equalsigns x   z
eq1 "0.5" "="        "1" "2"
eq2 "4"   "="        "2" "3"


When what I want is

          y         x   z

eq1  0.5  =  1   2
eq2  4.0  =  2   3


I am enclosing my R code below:

# Create matrix of  coefficients of independent variables.
a  <- matrix(c(1,2,2,3),nrow=c(2,2),byrow=TRUE)
dimnames(a)<-list(c("eq1","eq2"),c("x","z"))
cat("Matrix of independent variables\n")
a

# Create vector of dependent variables.
b <- matrix(c(0.5,4.0),nrow=c(2,1))

dimnames(b)<-list(c("eq1","eq2"),c("y"))
cat("Vector of dependent variables","\n")
b

cat("System of equations to be solved")
equalsigns <- c("=","=")
cbind(b,equalsigns,a)




Thank you,

John
