Your attachment did not come through and without either reproducible code or the image, it would be difficult to provide specific recommendations.

However, things to consider:

  1. Reduce the size of the fonts for your axis labels to make more room. See ?par and note the cex.axis parameter.
  2. Consider using meaningful abbreviations for your labels to shorten them.
  3. Consider rotating the labels using par("las"). You will likely need to adjust the plot margins using par("mar") as well to make room for the rotated labels.
  4. See R FAQ 7.27 "How can I create rotated axis labels?" which is a method to enable axis labels rotated to something between horizontal and vertical (ie. 45 degrees).
