OK, this was a silly example.
This one should be not as silly:
## Created example dataset
data1 = matrix(1:12, nrow=4, ncol=3)
data1 = data.frame(matrix(data1, 4, 3, byrow = T))
colnames(data1) = c("y1", "y2","x")
data2 = data.frame(c(1,1,2,2))
colnames(data2) =c("z")
data = cbind(data1,da
Hi room,
Is there any R package that solves a non linear objective pb, with
linear equality constraint?
A simple example
a =c (2, 5, 6, 7, 2)
b = c (7, 1, 4, 5, 6)
a and b are vectors of length 5
minimise f(x, a) = sum( (x-a)^2) such that sum( x*b) = 50.
where x is the control varia

xyplot.zoo uses xyplot and will displays graphs of
times series without space:
library(zoo)
z <- with(data, zoo(y, x))
xyplot(cbind(z, z, z, z, z))

OK - here is an example:
## Create example data
data = matrix(1:8, nrow=4, ncol=2)
## Name columns "x" and "y"
colnames(data) = c("x", "y")
data = data.frame(data)
## Create 5 graphs with the xyplot command
graph1= xyplot(y~x, data = data)
graph2 = xyplot(y~x, data = data)
graph3 = xyplot(

Dear R-community,
I created 5 different xyplots and graphed all of them with the print command on
one page (e.g.
print(graph1, split=c(1,1,1,5), more = T)
... print(graph5, split=c(1,5,1,5), more =T)
Using the above commands separates each graph by a white space. However, since
