Mary:
Here's one way.
## change the variable name to whatever title you want on your legend
data = melt(data, id="inputs",variable_name="customName")
data
g <- ggplot(data,aes(x=inputs, value, colour= customName, fill = customName,
shape=customName))
g <- g + geom_line(lwd=0.8)
g <- g + geom_point()
g <- g + scale_x_continuous(name='Number of inputs')
g <- g + scale_y_continuous('Conversion time (sec.)')Felipe D.
