search for: hasmethods

Dear All, I want to test whether a method exists for given object. For example, whether a function "deviance" is defined for an object of the "lm" class. My imperfect understanding leads me to think something like hasMethod("deviance", object) hasMethod("deviance", "lm") existsMethod("deviance", signature(class="lm"))

Hola. En mi caso, no he podido resolver los problemas con el Java para usar XLConnect, que en los papeles me parece el mejor. Supongo que algo de la arquitectura del sistema o bien de la relación entre el Java, el R y el RStudio. Así que utilizo library(openxlsx) write.xlsx(datos, file = "EDA1.xlsx") #donde datos es el objeto que quiero guardar. Requiere instalar el RTools, según tipo y

...r utilities that should be faster and more convenient, at least when more than one argument is involved. The new utilities will be: findMethods(), which returns a simple list of methods (replacement for getMethods()); findMethodSignatures(), which returns a character matrix of signatures; and hasMethods(), which tests for the existence of methods. Cheers, John

Buenos días a todos! Estoy trabajando con una base de datos que directamente he descargado de internet y después de prepararla un poco necesito exportarla a Excel he intentando con las dos opciones que mencionaré al final pero ninguna funciona, de qué otra manera puedo exportar esos datos a Excel... muchas gracias por su ayuda y pronta respuesta! 1) library(xlsx) library(rJava)

...default) is again an error before a user coordinate system has been set on the device, rather than giving nonsensical values (the effect of r31367). o Rare string width calculations in package grid were not interpreting the string encoding correctly. o hasMethods(f, env) {without specified 'package'} now works better. o A missing PROTECT could cause segfaults on string comparisons. (PR#11421) o str(structure(1, classID = "Pooh")) now works fine. o A missing PROTECT could cause segfaults in if() if coercion of...

...ct from model objects a suitable value for use in BIC calculations. An S4 generic derived from it is defined in package stats4. ? Code for S4 reference-class methods is now examined for possible errors in non-local assignments. ? findClasses, getGeneric, findMethods and hasMethods are revised to deal consistently with the package= argument and be consistent with soft namespace policy for finding objects. ? tools::Rdiff() now has the option to return not only the status but a character vector of observed differences (which are still by default sen...
