Hi all,
I am using SSE R plug in for a decision tree in Qlik sense.
In the sample qvf, the decision tree could be successfully generated by:
R.ScriptAggrExStr('SNSN','
library(rpart);
library(partykit);
library(d3r);
library(grid);
library(jsonlite);
d3_party(rpart(survived ~ ., data=q, method="class"));
',
sex, pclass, age_b, survived)
Now I want to use the generated decision tree to get the prediction result in the "Table", so I tried to use the code below:
R.ScriptEvalExStr('SNSN','
library(rpart);
library(partykit);
library(d3r);
library(grid);
library(jsonlite);
model<-rpart(survived ~ ., data=q, method="class");
predict(model,type="class"); '
, sex, pclass, age_b, survived)But it did not work, and SSEtoRserve.exe was saying:
Error: variables 'sex', 'pclass', 'age_b' were specified with different types from the fit
Any one with some ideas about this?
Thanks in advance.
