Primitive("+")、、 ###<R 3.6中没有add函数,所以下述代码运行需要先定义一个add函数>### # add <- function(e1, e2) e1 + e2 ### 手动定义add函数的两个参数 x1 = 'e1' x2 = 'e2' ### 照上述例子定义一个add2函数,只需要将do.call函数中的c修改为add add2 <- function(...)

Rewrite the cosine function in terms of the sine function. Here, the rewrite function rewrites the cosine function using the identity cos(x)=1−2 sin(x2)2, which is valid for any x. Get syms x R = rewrite(cos(x),"sin") R = 1−2 sin(x2)2 rewrite does not rewrite ...
Before R2021a, use commas to separate each name and value, and enclose Name in quotes. Example: Marker="o",MarkerFaceColor="red" The function line properties listed here are only a subset. For a complete list, see FunctionLine Properties. MeshDensity— Number of evaluation points 23 (defaul...
During activation, T cells undergo extensive gene expression changes that shape the properties of cells to exert their effector function. Understanding the regulation of this process could help explain how genetic variants predispose to immune diseases.
To evaluate how the heritability changes when considering more trait-related SNPs, we first took subsets from all SNPs at different sizes by using the sample() function in R and then used the LDAK-Thin model to estimate the heritability contributed by these SNP subsets61. The LDAK-Thin assum...
FunctionManager.add(fxy); The same applies to variables. The variables that you create go into the VariableManager. So if you do: MathExpression me = new MathExpression("a=5;4*a"); The parser immediately creates a variable calleda, stores 5 in it, and saves the variable in the Variabl...

ggheat() is a function from the ggplot2 package that can be used to create heatmaps. It is still relatively immature and mainly used for aligning plots and collecting legends. Something about ggheat():https://mp.weixin.qq.com/s/WhsBf6QAhVXeXeScM59cSA ...
