ggplot2 line plot order

ggplot2 line plot order

I have a series of ordered points as shown below:
However when I try to connect the points by a line, I get the following
output:
The plot is connecting 26 to 1 and 25 to 9 and 10 (some of the errors),
instead of following the order. The code for plotting the points is given
below:
p<-ggplot(aes(x = x, y = y), data = spat_loc)
p<-p + labs(x = "x Coords (Km)", y="Y coords (Km)") +ggtitle("Locations")
p<-p + geom_point(aes(color="Red",size=2)) + geom_text(aes(label = X))
p + theme_bw()
And for plotting the line I am just using: p + geom_line((aes(x=x,
y=y)),colour="blue") + theme_bw()
The file which contains the locations have the following structure:
X x y
1 210 200
..
..
..
where X is the numeric ID and x and y are the pair of co-ordinates.
What do I need to do to make the line follow the ordering of points?
