推荐答案

Hello Wexclo，

Hello Wexclo,

您可以从R设备输出中检查可视化。

You can check the visualization from R device output.

我在执行R脚本模块中使用了以下脚本：

I used the following script in execute R script module:

dataset1 <- maml.mapInputPort(1) # class: data.frame

# Contents of optional Zip port are in ./src/
# source("src/yourfile.R");
# load("src/yourData.rdata");

library(ggplot2)
library(data.table)

names(dataset1) <- sub(pattern=',', replacement='.', x=names(dataset1))


foo = qplot(age, data = dataset1, geom = "histogram", fill = income, position = "dodge");

print(foo)

bar = qplot(age, data = dataset1, geom = "density", alpha = 1, fill = income);

print(bar)



foo = qplot(x=age, data=dataset1, geom="density", alpha=0.5, fill=income);
print(foo)

# Select data.frame to be sent to the output Dataset port
maml.mapOutputPort("dataset1");

运行模块后可视化的输出是：

The output of the visualization after running the module is:
