[R] Functions in R like lincom and nlcom of Stata

[Marc Marí Dell'Olmo]

Hello all,

Does anyone know if there exists any function in R that resembles the
"lincom" and "nlcom" of STATA?. These functions computes point
estimates, standard errors, significance levels, confidence intervals,
etc. for linear and non linear combinations of previous estimated
parameters. Down here you've got links to descriptions of the
functions of STATA

Thank you,
Marc
