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
