[英]How can I create two matrices with meshgrid function in R?
I am beginer in R but I have experience in Matlab. 我是R语言的初学者,但是我有Matlab的经验。 In Matlab I could create two matrices with meshgrid function by the following way: 在Matlab中,我可以通过以下方式用meshgrid函数创建两个矩阵:
[lon, lat]=meshgrid(lon, lat)
where lon and lat are vectors with length_lon=424 and length_lat=412. 其中lon和lat是length_lon = 424和length_lat = 412的向量。 The resulted lon and lat martices are 424x412. 产生的纬度和纬度八格为424x412。 How can I carry out this method in R? 如何在R中执行此方法? I would appreciate if you helped me! 如果您能帮助我,我将不胜感激!
It looks like there are R implementations of meshgrid
available: http://www.inside-r.org/packages/cran/pracma/docs/meshgrid or http://artax.karlin.mff.cuni.cz/r-help/library/AtmRay/html/meshgrid.html 看起来有可用的R meshgrid
实现: http : //www.inside-r.org/packages/cran/pracma/docs/meshgrid或http://artax.karlin.mff.cuni.cz/r-help /library/AtmRay/html/meshgrid.html
Or according to this R for MATLAB users article: 或根据此R for MATLAB用户文章:
I think if you want an idiomatic R solution, you should explain why you want to use meshgrid
... 我认为,如果您希望使用惯用的R解决方案,则应该解释为什么要使用meshgrid
