Raster into .tif format to use in R

Deepa

Hi,

 

I am using ArcMap 10.8 version. I exported raster into .tif format to work on it further in the R studio. The raster values ranges from 0 to 1 and there are no data in parts of the area outside county borders. It is a single band raster.

After importing the .tif file into R studio and plotting the raster shows that the values ranges from 0 to 255. Why is it like that? Also the Nodata values outside the county border also shows some high values. 

 

What did i do wrong and how can i fix this?

Yes Jeff, it was due to the way i exported the file as tiff format. I used the option under file  to export as tiff and the color mode options were only 4. So instead i used the export of the raster file directly from table of contents and then it worked well for me. The exported image had the same scale and no changes in color modes. Thanks for the suggestions here.
