plotdata |
An MAgPIE object |

Converts a MAgPIE object or a list of MAgPIE objects into a dataframe usable for ggplot
as.ggplot(x,scenario="default",asDate=T,rev=F,useDimNames=FALSE)as.ggplot(x,scenario="default",asDate=T,rev=F,useDimNames=FALSE)
x |
MAgPIE object or list of MAgPIE objects. For a list of MAgPIE objects the name of the list entry (has to be character) is used as scenario name. |
scenario |
Name of the scenario (only used if x is not a list) or position of the entry in the third dimension that contains the scenario name (only if the scenario name is stored in the third dimension) or NULL (automatic detection) |
asDate |
Format the years as date (TRUE) or keep as is (FALSE); deprecated (only kept for compatibility with older scripts) |
rev |
reverse legend order (TRUE) or not (FALSE) |
useDimNames |
Use dim names of 3rd dimension instead Data1, Data2, Data3, Data4; works only if x is a MAgPIE object (no list) and scenario=NULL |

na.rm |
Boolean which decides whether NA values should be removed from the data. |
