当我查询/mycollections?ql=Select * where name='dfsdfsdfsdfsdfsdf'我得到

我正在尝试将.png图像(徽标)添加到使用ggplot创建的图形的pdf报告的标题中并打印到pdf.

我找到了以下示例如何将图像添加到ggplot图中.但是,我希望将.png图像添加到ggplot区域之外的pdf标题中.

#-------------------------------------------------------------------------------
#  Example png file
#-------------------------------------------------------------------------------
library(reshape2)
library(png)
mypngfile = download.file('http://api.altmetric.com/donut/502878_64x64.png', 
                           destfile = 'mypng.png', mode = 'wb')
mypng = readPNG('mypng.png')

#-------------------------------------------------------------------------------
# create example plot using mtcars data frame from ggplot
#-------------------------------------------------------------------------------
library(ggplot2)
p.example = qplot(mpg, wt, data = mtcars) + 
  annotation_raster(mypng, ymin = 4.5, ymax= 5, xmin = 30, xmax = 35)

#-------------------------------------------------------------------------------
# print to pdf file with footnote
#-------------------------------------------------------------------------------
fname = "C:/temp/my report.pdf"
pdf(fname, 10.75, 6.5, onefile=TRUE, paper="a4r")
print(p.example)
dev.off()

...产生一个如下所示的pdf:

但是,我希望图像显示在ggplot区域之外 …

我使用usergrid来存储客户项目的数据.它有两个系列carShowrooms和汽车.到目前为止,我很好.但我有一个场景,我已经刷新了收集车的masterdata.每次我这样做,我都必须删除汽车中的所有现有数据,并将其替换为主库存系统中的传入汽车数据.

现在,通过https://www.npmjs.org/package/usergrid中的文档 ,我发现我一次只能销毁一辆汽车.

car.destroy(function(err){
    if (err){
        //error - car not deleted
        //winston log - tbd
    } else {
        //success - car deleted
    }
});

这对于较小的陈列室来说是好的,但更大的多品牌陈列室有各种各样的汽车 - 有时甚至多达50种不同的品种(8个汽车品牌*大约8种不同的选择).

有批量删除选项吗？如果我在这里遗漏了什么,有人可以指点我.

PS我是usergrid的新手,如果这是一个重复的问题,请标记并指出我正确的网址

我可以使用curl发布文件

curl -X POST -i -F name='barca' -F country='spain' -F 
file=@/home/messi/Desktop/barca.png 'http://localhost:8080/new_org/hel/concerts'

我可以得到(文件)

 curl -X GET -H 'Accept: image/png' 'http://localhost:8080/new_org/hel/concerts/<id or name of entity>'

但是当我尝试使用同样的东西时requests.post,我得到了错误.有人知道为什么会这样吗？(当文件指针不在最后时遇到错误,但是当文件指针终止时,我得到了响应200但是没有发布文件)

import requests
url = 'http://localhost:8080/new_org/hel/concerts'
file = dict(file=open('/home/messi/Desktop/barca.png', 'rb'))
data = dict(name='barca', country='spain')
response = requests.post(url, files=file, data=data)

错误:(来自usergrid)响应代码:400
