コマンド readRAST (rgrass7) を使用してマップを R に取得しましたが、今は機能しません。結果が0のいくつかのオプションを試しました。すべての R パッケージを更新しました。GRASS 7.8.5 をインストールしました。GRASS内でRguiを起動。取得
elev <- readRAST("elevation", ignore.stderr=TRUE)
Error in sp::CRS(getLocationProj()) : NA
問題なく readVECT 経由でベクター マップを取得できます。
それを修正する方法はありますか？そうでない場合、GRASS ラスター マップを R に変換する現在の方法は何ですか?
ありがとうございました。
