How to write out this regression equation in R?

How to make R write out: Balance = 2 + 3 * IntGDP + 5 * IntUnemployment + 0.3 * d1 from the table below: Balance Intercept IntGDP GDPNum IntUnemployment IntInflation d1 d2 d3 30000 2 3 5 0.3 0 0
Maybe ?sprintf would help?
And if you wrap that in a function that takes a vector, using apply() on the table would give you one string per row,

But sprintf is itself vectorized. If you give it vectors, it returns vectors. So you could obtain that apply-result more efficiently by passing a bunch of column vectors of data. There happens to be a convenient object called a data frame that holds a bunch of similar-length vectors.
DF <- data.frame( m=c(1,2), b=c(-3,4) )
result <- sprintf( "y=(%d)*x+(%d)", DF$m, DF$b)
cat(paste(result, collapse="\n"))
