New `nchar` behavior in R 3.3.0 causes error in .plotFit #2

Closed daynefiler closed 8 years ago

nchar(NA) changed from returning 2 to returning NA in R 3.3.0 -- resulting in an error when plotting a concentration series that was unable to calculate the covariance matrix.

Fix by assigning the values as "NA" instead of NA.
