Likewise, glad to report that Sys.unsetenv("GFORTRAN_STDOUT_UNIT") works. Subject: RE: Failure to execute NONMEM from R But in nmfe74.bat there is an additional redirection command, which is fatal when not properly done in R, whereas in nm73.bat, the sole re-direction command not properly done merely results in the contents of FMSG not transferring to the main NONMEM result file.Īt the beginning of an R session, as recommended by Tarj Sohata, or you can use a modified nmfe74.bat file located at: This occurs in both nmfe73.bat and nmfe74.bat. The output re-direction and/or console output to gfortran programs is mis-managed in R’s system call. The difficulty occurs only in Windows, using gfortran compiled NONMEM, executed from a system call from within R. This will provide the capability to accurately determine population pharmacokinetic parameters for a number of potentially toxic drugs with which newborns and children are treated.I have determined the reason for nmfe74.bat and nmfe73.bat behaving differently in handling standard output when executed from R (it turns out I solved this for Chuanpu Hu a few months ago). Thus, NONMEM is an ideal method for estimating population pharmacokinetic parameters in the newborn and general pediatric populations, where the frequency and volume of sampling are important considerations. NONMEM's advantage is that it can be utilized when only a few blood samples are available from each patient, provided the overall size of the study population is large. NONMEM uses the method of extended least squares and allows for pooling of data from many individuals, but explicitly adjusts for the correlation of data obtained from each individual. Sheiner et al (J Pharmacokin Biopharm 5:445,1977) developed a computer program, NONMEM, to estimate population pharmacokinetic parameters from data generated during routine clinical care of patients. As a result, data from adult patients or volunteers are often erroneously extrapolated for pediatric use. These studies generally require careful and extensive sampling of blood from subjects to determine pharmacokinetic parameters, making them less useful and less feasible in pediatric practice. Traditional pharmacokinetic studies provide valuable information for optimizing the clinical use of pharmacologic agents.
