使用R将光栅图像从equirectagular重新投影到latlon

Hi i been trying to reproject a raster image from Equirectangular to EPSG:4326 (Latlon), the issue is that every time i run my code on R, i get the wrong coordinates on the new image; i don´t know where is the error in the code, also i do the same process with Qgis, and i got the same result, it´s strange, i got the opportunity to do the same reprojection process in ENVI, and the result was succesful, help please!!!Hi i been trying to reproject a raster image fr
