我希望在如何使用plan
包创建甘特图时提供一些帮助。该软件包在前面的综合文章中简要提及several approaches using R; see answer 4 of 7 for plan
我的可重现数据如下。
dput(project)
structure(list(key. = structure(1:8, .Label = c("1,", "2,", "3,",
"4,", "5,", "6,", "7,", "8,"), class = "factor"), description. = structure(1:8, .Label = c("recommendation1,",
"recommendation2,", "recommendation3,", "recommendation4,", "recommendation5,",
"recommendation6,", "recommendation7,", "recommendation8,"), class = "factor"),
start. = structure(1:8, .Label = c("10/1/2015,", "10/2/2015,",
"10/3/2015,", "10/4/2015,", "10/5/2015,", "10/6/2015,", "10/7/2015,",
"10/8/2015,"), class = "factor"), end. = structure(1:8, .Label = c("12/1/2015,",
"12/2/2015,", "12/3/2015,", "12/4/2015,", "12/5/2015,", "12/6/2015,",
"12/7/2015,", "12/8/2015,"), class = "factor"), done. = c(90,
30, 0, 0, 0, 0, 0, 0), neededby = c(0, 0, 0, 0, 0, 0, 0,
0)), .Names = c("key.", "description.", "start.", "end.",
"done.", "neededby"), row.names = c(NA, -8L), class = "data.frame")
使用read.gantt()
,数据框对我来说很好看:
> project
key. description. start. end. done. neededby
1 1, recommendation1, 10/1/2015, 12/1/2015, 90 0
2 2, recommendation2, 10/2/2015, 12/2/2015, 30 0
3 3, recommendation3, 10/3/2015, 12/3/2015, 0 0
4 4, recommendation4, 10/4/2015, 12/4/2015, 0 0
5 5, recommendation5, 10/5/2015, 12/5/2015, 0 0
6 6, recommendation6, 10/6/2015, 12/6/2015, 0 0
7 7, recommendation7, 10/7/2015, 12/7/2015, 0 0
8 8, recommendation8, 10/8/2015, 12/8/2015, 0 0
但是当我使用print(summary()时出现问题。最后两行有问题。我尝试在.csv文件中重写它们,但没有用。
> print(summary(project))
key. description. start. end. done. neededby
1, :1 recommendation1,:1 10/1/2015,:1 12/1/2015,:1 Min. : 0.0 Min. :0
2, :1 recommendation2,:1 10/2/2015,:1 12/2/2015,:1 1st Qu.: 0.0 1st Qu.:0
3, :1 recommendation3,:1 10/3/2015,:1 12/3/2015,:1 Median : 0.0 Median :0
4, :1 recommendation4,:1 10/4/2015,:1 12/4/2015,:1 Mean :15.0 Mean :0
5, :1 recommendation5,:1 10/5/2015,:1 12/5/2015,:1 3rd Qu.: 7.5 3rd Qu.:0
6, :1 recommendation6,:1 10/6/2015,:1 12/6/2015,:1 Max. :90.0 Max. :0
(Other):2 (Other) :2 (Other) :2 (Other) :2
无论如何,我跑了plot()
,结果显然很奇怪
答案 0 :(得分:2)
我是名为plan
的R包的作者。通常会在包issue page上提出问题,我认为这会限制受众群体,但在提出问题时会向我发送电子邮件。
在任何情况下,为甘特图构建数据的常规方法是使用名为read.gantt()
的函数。要获得有关该功能的文档,请尝试
library(plan)
?read.gantt
请注意,格式有严格的规定。它必须是纯文本文件,而不是csv,当然不是xls。使用简单的文本编辑器编辑它。如果我是你,那么当你写project
并告诉你列时,我会从你输出的输出开始。将其剪切/粘贴到纯文本文件中(可能名为“plan.txt”,但名称无关紧要)。然后根据read.gantt()
的文档调整标题,依此类推。然后阅读并绘制它。学习格式和查看输出的最快方法可能是查看软件包附带的插图。在R中,键入
vignette("plan")
你会明白的。我在这个消息的底部放了一个小插图页面的快照。它可能很难在SO上阅读,但只需运行上面的命令并跳到第4页就可以看到它。
如果您擅长文本编辑器,这只需要几分钟的时间。但请注意,数据的格式是非常严格,因此您可能需要使用一些奇特的编辑器技巧,如移动列。
使用R命令将数据强制转换为格式是可能的,但是根据您上面所写的内容,您似乎对R很新,最好坚持准备数据的简单路径并运行标准R命令。
如果您需要更多帮助,请与我们联系。 (同样,我不会定期阅读SO,所以除非通知我后续跟进,否则我不会回复,除非你给我发电子邮件....这就是为什么最好在{上使用问题{1}}网站,当然。)
