Row number showing rather than value

Question

I am following use the answer to the question Add dynamic subtitle using ggplot in the following way:

      ggtitle(bquote(atop(.(df$fname[row]),
                          atop(italic(.(param_string)), ""))))

When I look at my graphs, I am seeing:

enter image description here

Rather than the actual value of df$fname[row], which has been verified independently to be something else.

What's going on here?

What is the value of `df$fname[row]`? – Jul 16 '15 at 06:30 — , Jul 16 '15 at 06:30

Try this :

 ggtitle(bquote(atop(.(paste(df$fname[row])),atop(italic(.(param_string)), ""))))

Thanks that worked. Can you explain why this is the case? – Tinker Jul 16 '15 at 06:45
many times when the column has string objects its pastes the factor number instead . for eg if a column had red blue green as values then it will print 1 for red , 2 for blue , 3 for green. U just have to try both ways and see how u get the result – Anuja Parikh Jul 16 '15 at 09:50
