如何将Matlab的点运算符转换为R? [英] How to translate Matlab's dot operators into R?

问题描述

Matlab具有一组点运算符，例如.*，./，.^.这些算子中的每一个都由一个点和一个正常的代数算子组成. 我想将它们翻译成R:

Matlab has a set of dot operators, such as .*, ./, .^. Each of these operators consists of a dot and a normal algebraic operator. I would like to translate these into R:

col = round(r0 + (j/k) * lambda .* cos(pi/6))+1;
ro    = 700 - round(s0 - (j/k) * sin(phi)./cos(pi/6))
col = min(col):1:max(col)
ro    = min(ro):1:max(ro)

请帮助

推荐答案

您可以将代码行转换为字符并使用gsub

You could convert your lines of code to characters and use gsub

a <- "col = round(r0 + (j/k) * lambda .* cos(pi/6))+1;"
a <- gsub("\\.","",a)

您可以将其包装在函数中.

which you could wrap in a function.

所以，这是一个可以实现的功能，

So, here's a function to do it,

DotOut  <- function(x) {
 gsub("\\.","",x)
}

然后您可以在应用功能之一中使用此功能.

You could then use this function in one of the apply functions.
