"class member function not found" Error trying to create a histogram

[Lufla Ferretti]

Hi, I'm trying to create a super simple histogram just to start figuring out stata (I have the 13 version). After following all the necessary steps, this message of error comes out:

sysuse nlsw88.dta
(NLSW, 1988 extract)

. histogram age
(bin=33, start=34, width=.36363636)
relative_posn.new,: class member function not found
(error occurred while loading textstyle.class)
textstyle.new: class member function not found
(error occurred while loading tickstyle.class)

(error occurred while loading ticksetstyle.class)
ticksetstyle.new: class member function not found

(error occurred while loading twowaygraph_g.class)
twowaygraph_g.new (histogram age [], barwidth(-99) plotregion(margin(b=0))
density start(34) bin(33)) if __000000, ytitle(`"Density"') xtitle(`"age in
current year"') legend(cols(1)) legend(nodraw): class member function not
found

twoway is not a valid graph subcommand
r(198);

How can I fix it? It also goes for all other graphs I tried to create(box plots, etc...) always the same error.

Thanks in advance!

Restart your computer, then update your Stata by running;

update q

and follow instructions.

You may also verify that Stata has been installed properly by running the Stata Installation Qualification Tool (IQT): https://www.stata.com/support/instal...lification/13/

If this does not help you may reinstall Stata and/or contact StataCorp https://www.stata.com/support/tech-support/contact/

Hi. I am trying to draw diagram in stata (version 14) for quantile regression. The command is displaying
sqreggraph_g.new BMI female: class member function not found
What will be the right command if I want to find out the two-way graph for BMI and its determinants?
Thanks in advance.
