[need help] Error occurs when creating Sankey diagram by R script

Anonymous — Thu, 30 May 2019 09:11:51 GMT

Hi Team,

I did data transform by creating a new table with DAX, and the format of new table is sankey format: Source, Target, Occurs(Please refer to below table1)

Table1:

Then I trying to create sankey diagram with R visulization, here is the script:

# The following code to create a dataframe and remove duplicated rows is always executed and acts as a preamble for your script:

dataset <- data.frame(Source, Target, Occurs)
dataset <- unique(dataset)
library(networkD3)
dataset$Source = as.character(dataset$Source)
dataset$Target = as.character(dataset$Target)
Sankeylinks<-dataset
Sankeynodes<-data.frame(name=unique(c(Sankeylinks$Source,Sankeylinks$Target)))
Sankeynodes$index<-0: (nrow(Sankeynodes) - 1)
Sankeylinks<-merge(Sankeylinks,Sankeynodes,by.x="Source",by.y="name")
Sankeylinks<-merge(Sankeylinks,Sankeynodes,by.x="Target",by.y="name")
Sankeydata<-Sankeylinks[,c(4,5,3)];
names(Sankeydata)<-c("Source","Target","Occurs")
Sankeyname<-Sankeynodes[,1,drop=FALSE]
# draw sankey network
sankeyNetwork(Links=Sankeydata,Nodes=Sankeyname,Source="Source",Target="Target",Value="Occurs",NodeId="name",fontsize=8,nodeWidth=20)

But there is error occured.

what is the issue with my script?

Hi,

The error on your picture says that field name is unavailable.

Please check that you correctly typed all your fileds names.

Also, pay attention please that using fileds must be added to "Values" bucket to be available in a script regarding this article.
