如何修复 r markdown 中的矩阵错误问题？

Question

Rmarkdown keeps telling me this whenever I try to load r file: Error in h(simpleError(msg, call)): error in evaluating the argument 'x' in selecting a method for function 'as.matrix': cannot open the connection

this is what the r file contains:

a <- as.matrix(read.csv("data/a_a.csv", row.names = 1))
b  <- as.matrix(read.csv("data/b_b.csv" , row.names = 1))

Answer 1

In the R file, you would want to show the entire path example: a <- as.matrix(read.csv("project/R/data/a_a.csv", row.names = 1)). when you load it into Rmarkdown, it will be able to read it.

Thanks!
