[R] Plot a line using ggplot2

[Ebert,Timothy Aaron]

A number of problems.
The variable names are not helpful. PointEstx is not a point it is a value. I need an x and a y coordinate for a point.
row1 is not defined
While there is a function data.frame(), there is no data_frame(). Making this change gives an error that row1 is not defined. I solved the problem with row1<-row2+1.

The ggplot statement looks wrong.

Does this give you what you need?
ggplot(linedata,aes(x=PointEstx, y=PointEsty)) + geom_line()

Note I changed the comma to a plus sign and changed the brackets.

Regards,
Tim

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())
