Plot a line using ggplot2

Colleagues,

I am trying to plot a simple line using ggplot2. I get the axes, but I don't get the line. Please let me know what my error I am making.
Thank you,
John

# Define x and y values
PointEstx <- Estx+1.96*SE
PointEsty  <- 1

row2 <- cbind(PointEstx,PointEsty)
linedata<- data_frame(rbind(row1,row2))
linedata
# make sure we have a data frame
class(linedata)

#plot the data
ggplot(linedata,aes(x=PointEstx, y=PointEsty), geom_line())
