How to determine the geom type of each layer of a ggplot2 object?

由 心不动则不痛 提交于 2019-12-18 03:38:29
问题 As part of an effort to remove a specific geom from a plot I've already created (SO link here), I'd like to dynamically determine the geom type of each layer of a ggplot2 object. Assuming I don't know the order in which I added layers, is there a way to dynamically find layers with a specific geom? If I print out the layers like I do below I can see that the layers are stored in a list, but I can't seem to access the geom type. library(ggplot2) dat <- data.frame(x=1:3, y=1:3, ymin=0:2, ymax=2

问题 I'm trying to load in TEST phase a network configuration which has a memory data layer first and then a convolution layer. The MemoryData layer creation succeeds, But the convolution layer's creation fails at the following location: LOG(INFO) << "Creating layer " << param.name(); const string& type = param.type(); CreatorRegistry& registry = Registry(); CHECK_EQ(registry.count(type), 1) << "Unknown layer type: " << type << " (known types: " << LayerTypeList() << ")"; Printed error is: F0519

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 什么是 HTTP HTTP（Hyper Text Transfer Protocol 超文本传输协议） 是互联网上应用最为广泛的一种网络协议，是一个客户端和服务器端请求和应答的标准，用于从 www 服务器传输超文本到本地浏览器的传输协议，它可以使浏览器更加高效，使网络传输减少。HTTP 由万维网协会和 Internet 工作小组 IETF 共同合作制定的规范。 HTTP 和 HTTPS 说起 HTTP，就不得不说 HTTPS，HTTPS 比 HTTP 多了个 S，这个 S 就为 SSL，它是一种网络加密协议，会对网页传输的数据进行加密，我们平常打开的网页，比如我的博客，在 URL 的开头，显示 https，这个就属于协议类型，当然，协议类型不止这一种，比如还有其他，如 ftp、sftp、smb 开头的 URL，在爬虫中，我们抓取的页面通常就是 http 或 https。 HTTP 和 HTTPS HTTPS（Hyper Text Transfer Protocol over Secure Socket Layer），是以安全为目标的 HTTP 通道，简单讲是 HTTP 的安全版，即 HTTP 下加入 SSL 层，简称为 HTTPS。HTTPS 的安全基础是 SSL，因此通过它传输的内容都是经过 SSL 加密的

Google Maps: Some KMZ layers disappear after many access

由 試著忘記壹切 提交于 2019-12-14 04:23:39
问题 Recently I'm developping a Map containing KML Layer compressed as KMZ file (about 45mb). As there is a file weight limitation, I first split the files into 3mb files. Then I noticed that some splitted files was not showing everytime, causing some "blanks" on the map. So I made researches on many forums, and found that the real limitation of files in order to get everything working properly is 2mb. After update, the KML Layer was indeed showing entierely. However, after doing many tests, I

问题 I need to crop a pdf document using the linux shell and then extract the text just in that cropped pdf. My idea was to crop a pdf using pdfcrop linux tool and then use a txt2pdf text extractor tool to extract the text just in the cropped area, but i've realized that i'm thinking on images, and when i try to do this the result is the same than doing it over the original, not cropped, pdf. I guess it's a layer problem. As the pdf format works with layers, if i don't "crop" all the layers, the

问题 Using Spring MVC to develop a web application. Earlier I was using Controller layer, Service layer(business logic), Model layer(entity) and DAO(DB) layer. But someone pointed out that i should introduce two more layer ie. dto layer for collecting data from front end and transforming layer which will convert than dto into model(entity) layer objects. Now I am using: Controller layer (which will send the data to DTO layer) DTO layer (which will send the its data to transforming layer)

Twitter Bootstrap Button dropdown z-index layering issue

由 我与影子孤独终老i 提交于 2019-12-12 22:02:14
问题 I've been pounding and pounding on this. I have a comment section on my site with an option to edit with a Twitter Bootstrap dropdown button, but I as you can see below, it's hidden by the following comments. I know it's not an overflow issue, as you can see the bottom of it under the last comment. So it can only be z-index layering issue. But I put all the comments on z-index: 4 and the dropdown on z-index: 1000 , so I have no idea what to do! Here is a jsFiddle: http://jsfiddle.net/ssL1yydx
