Object type (dataframe, function and other) This is a quick demo of objectremover in action. I made sure to include a couple of safety features to help ensure that you don’t remove objects by mistake. Firstly, it displays what objects will be removed based on the options you’ve selecte...
If you don’t want to use this method, because you aren’t sure what attribute you’ll be merging on in the future, or some other reason, you can also create a new column to use as a home base and re-sort your data.table on. After any manipulations that you do, to make sure t...
4. The first column of the inverse will be all 1’s. Drop that first column. The remaining columns are your contrast matrix. You can then apply that matrix to the factor itself in the dataframe using contrasts(data$factor) <- mat, or you can just specify it as part of the model usi...
+与其他标准统计软件(如SAS、SPSS和Stata)中的数据集类似,**数据框**(`dataframe`)是R中用于存储数据的一种结构:列表示变量,行表示观测。在同一个数据框中可以存储不同类型(如数值型、字符型)的变量。数据框将是你用来存储数据集的主要数据结构。 +::: + +## 向量 + +向量,`vector`,就是同一类型的...

data$column.name <- as.numeric(data$column.name) Many (basic) R functions are smart are will automatically convert character data to factors, then continue running. Sometimes its easier to leave things as character data and let R sort it out for you....
