在R和Knitter中,我可以抑制readOGR的消息吗?

你试过设置吗 verbose = FALSE 在 readOGR 功能本身?

例如

> dsn <- system.file("vectors", package = "rgdal")[1]
> cities <- readOGR(dsn=dsn, layer="cities")
OGR data source with driver: ESRI Shapefile 
Source: "C:/Users/sohanlon/Dropbox/R/R64_Win_Libs/rgdal/vectors", layer: "cities"
with 606 features and 4 fields
Feature type: wkbPoint with 2 dimensions
# Set verbose = FALSE
> cities <- readOGR(dsn=dsn, layer="cities" , verbose = FALSE)

那么,相关的编织者群体可能是:

```{r, echo=FALSE, message=FALSE}
library(rgdal)
dsn <- system.file("vectors", package = "rgdal")[1]
cities <- readOGR(dsn=dsn, layer="cities", verbose=FALSE)
```

做到这一点的“编织者”方法是使用 results = 'hide' 。借用@SimonO101的示例数据,请尝试:

```{r, results='hide', echo=FALSE, message=FALSE}
library(rgdal)
dsn <- system.file("vectors", package = "rgdal")[1]
cities <- readOGR(dsn=dsn, layer="cities")
```

如果您正在使用 st_read 而不是 readOGR 使用 quiet=TRUE 作为隐藏日志的附加参数
