Hello,
does anyone know why I get this error: "Input arguments must be numeric, datetime, duration or categorical"?
Thank you.

Jan1989 seems to have strings and Var2,Var4 and Var5 seem to be NaNs

The errorbar call should be:
errorbar(x, MODESTAMMEQ.Var5, MODESTAMMEQ.Var4,'.r','MarkerSize',6)
since ‘MODESTAMMEQ.Jan1989’ (that likely threw the error) has to be processed in the regexp and datetime calls to be usable as ‘x’.
However the ‘MODESTA’ table does not exist, so the second plot call does nothing, and substituting:
plot(x,[y, MODESTAMMEQ.Var5]);
gives a very strange result (at least to me).
