首先......我可能会错误地处理这个任务。我是图表功能的新手,如果我对图表功能的理解是错误的,从编程的角度来看,我不会感到惊讶。
问题出现在代码的“节点 [fillcolor = COLOR]”语句中。
如果我只是写'fillcolor = Green,style =filled'而不是fillcolor = object1,那么它就完美了。同样,如果我用“深红色”或任何其他颜色替换绿色,也没有问题。
我的问题是我希望这种颜色发生变化,具体取决于由条件确定的对象的值。基本上,如果去看医生的病人太少,这应该会在我每天创建的报告中引发危险信号,并且每天手动编程会有点痛苦。
我尝试过
的:我没有指定颜色,而是尝试使用条件对象的输出作为填充颜色(例如我在下面尝试过的)
fillcolor = object1 - 用黑色填充最终框
fillcolor = ', object1 ' - 最终框再次被黑色填充
fillcolor = object1[1] - 输出结果错误
fillcolor = ', object1[1] ' - 最终框为黑色- 再次填充
# Just create some random data for a flow chart
a = 100 # Total people
b = 60 # Number of total that are sick
c = 19 # Number of sick that saw a doctor
d = round(c/b * 100) # percent of sick who saw a doctor
# create a flowchart-list-object
flow <- list(a=a, b=b, c=c, d=d)
# this could be where I am going wrong
# Condition that determines if the Percentage of sick people who saw a doctor
# is above 40%
if (d > 40) {
object1 <- 'Green'
} else
object1 <- 'Crimson'
# Output the flowchart using grViz
DiagrammeR::grViz("
digraph dot {
graph[layout = dot, fontsize = 15]
# Node numbers with labelled text
node [shape = box,
width = 3,
fontname = Helvetica]
a [label = '@@1']
b [label = '@@2']
c [label = '@@3']
# First set of node to edge connections
a -> b -> c
node [fillcolor = object1, style = filled]
d [label = '@@4']
c -> d
}
[1]: paste0('Total Sick \\n ', flow$a, '')
[2]: paste0('Number of total sick \\n ', flow$b, '')
[3]: paste0('Number of Sick who see a doctor \\n ', flow$c, '')
[4]: paste0('% of sick who see a doctor \\n ', flow$d, '')
")
如果病人的百分比高于 40%,我希望流程图中的最后一个框为绿色,如果低于 40%,则为深红色(红色)。
