In fact my date frame is much larger. I made several regressions and created a data frame with its fitted values.

Now in a graph of Y versus X we plot these adjusted values. In ggplot I can not.

I do this:

for(i in 1:7)
print(ggplot(data, aes(x=X, y=Y)) + geom_point() +
  geom_line(data=data, aes(x=X, y=data[,i+2], colour="red")))

but only the curve of column three comes out.

Any help?

ggplot2 requires the data to be in the long or narrow format, depending on the source . So the trick in your problem was to just convert the dataset to long, do a little manipulation of the result, and everything worked out.

library(reshape2)
library(ggplot2)
names(data)

data.long <- melt(data[, -1], id.vars="X")

ggplot(data, aes(x=X, y=Y)) + geom_point() + 
geom_line(data=data.long, aes(x=X, y=value, colour=variable))

Note that the data.long object was created without the first column ( y ) of the data frame data , since it only contains information about the original points and is not required when creating the regression curves .
