J'essaie de transmettre un data.frame avec des dates dans les noms de fichier dans une fonction PerformanceAnalytics (package).PerformanceAnalytics + data.frame: Problème de formatage lors de l'utilisation des fonctions de package
Mes données est ci-dessous, je reçois le message d'erreur suivant lorsque vous essayez d'exécuter le code
> charts.PerformanceSummary(x$Return)
Error in checkData(R) :
The data cannot be converted into a time series. If you are trying to pass in names from a data object with one column, you should use the form 'data[rows, columns, drop = FALSE]'. Rownames should have standard date formats, such as '1985-03-15'.
Comment cela peut-il être résolu? Je pensais que PerformanceAnalytics reconnaîtrait automatiquement mes lignes comme des dates.

Merci. J'ai essayé x [, 'Return'] avant et ça m'a donné aussi un vecteur, mais x [, c ('Return', 'Open')] restitue un data.frame, y at-il une raison particulière à cela? – uncool
@uncool vous pouvez également utiliser 'x [, 'Return', drop = FALSE]' pour retourner une seule colonne en tant que 'data.frame'. Voir '? \' [\ '' Pour plus d'informations – DunderChief
@uncool: c'est pourquoi j'ai suggéré 'x [" Return "]', qui renvoie un data.frame. –
