我正在使用.mp3
代码运行os.system("Warning.mp3")
文件但出现错误:
我的代码是
sh: Warning.mp3: command not found
但我收到这样的错误,
library(raster)
r <- raster(as.matrix(mtcars))
r[0:95] <- 0
r[96:180] <- 2
r[181:352] <- 1
breakpoints <- c(0, 1, 2)
colors <- c("white","black","grey")
plot(r, breaks=breakpoints, col=colors, axes = FALSE, legend = FALSE)
你能帮我讲一下使用os.startfile启动mp3文件吗?
