记录一下今天碰到的error: 今天在处理单细胞数据的时候,出现了如题所示的报错 (in Rstudio) 在数据合并的之后scale数据的时候报错的,代码如下: 代码语言:javascript 复制 // 合并数据sce.big<-merge(gse175453list[[1]],y=c(gse175453list[[2]],gse175453list[[3]],gse175453list[[4]],gse175453list[[5...

We can find the square root of the ''rbis'' vector by using thesqrtfunction. For demonstration, we'll just call the function so that the output is displayed in the console. The following lines of code were written in R studio in the console window. Results follow the code samples. ...
As you can see based on the output of the RStudio console, we stored the values of the column x1 in the vector object vec. This is probably the easiest solution, in case you want to convert a data frame column to a vector in R. However, there are several other alternatives… Example...
In Example 1, I’ll show how to use the%in%-operatorto extract all rows from our data frame where the values of the variable x1 are contained in our example vector. Have a look at the following R code: data[data$x1%in%vec,]# Applying %in%-operator# x1 x2# 1 1 a# 7 7 g# 10...
R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 下表提供了其它常用的统计函数。 R语言中每个数值运算函数都有na.rm选项,以便在计算前删除缺失值。否则,缺少值的存在将导致结果也是缺失值。统计函数的运算的对象可以是向量也可以是dataframe Function Description mean(x, trim=0, na.rm...

The second statement (using the <-operator) is the most common way of assigning in R, and we’ll therefore use this form rather than the=operator or theassign()function. Once we have assigned a vector to a name, we can refer to the vector using this name. For example, if we type ...
Introduction In data analysis, there are times when you need to split a vector into smaller chunks. Whether you’re managing large datasets or preparing data for parallel processing, breaking down vectors can be incredibly useful. In this post, ...
The RStudio console returns the result of the previous R code: A vector of length five consisting only of zeros. Example 2: Creating Vector of Zeros Using rep() Function & 0L Alternatively to the R syntax shown in Example 1, we can also specify 0L instead of 0 within the rep function...
