Deckdowns- Error de análisis de rendimiento: factor y numérico

Question

Algunos datos en un archivo de texto:

date,p
2013-11-14,0.001
2013-11-13,-0.005
2013-11-12,0.001

library(PerformanceAnalytics)
stuff<-read.csv("C:stuffexample.txt")
str(stuff)

'data.frame':   3 obs. of  2 variables:
 $ date: Factor w/ 3 levels "2013-11-12","2013-11-13",..: 3 2 1
 $ p   : num  0.001 -0.005 0.001

quiere usar el análisis de rendimiento en los datos:

AverageDrawdown(stuff)

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'. 

table.Drawdowns(box)

Error in checkData(R[, 1, drop = FALSE]) : 
  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'. 

¿Cómo arreglo errores?

Answer 1

Necesitas seguir los consejos que se proporcionan en el error.Debe tener nombres de fila de fechas y solo datos en sus datos. Frame:

row.names(stuff) <- levels(stuff$date)[stuff$date]
stuff2 <- stuff[, 'p', drop=FALSE]

AverageDrawdown(stuff2)

Esto está probado porque no proporcionó un ejemplo reproducible aunque ...
