An error occurred while running the perform_PCA function

[liliy182]

When I run the following piece of code with sample data：
PCA_Output <- perform_PCA(Input_Image_File = Input_Image_File,

•                       Input_Mask_File = Input_Mask_File,
  

•                       Output_Dir = Output_Dir,
  

•                       TypePCA = TypePCA,
  

•                       FilterPCA = FilterPCA,
  

•                       nbCPU = nbCPU,
  

•                       MaxRAM = MaxRAM,
  

•                       Continuum_Removal = Continuum_Removal)
  

I get the following error：
[1] "Extract pixels from the images to perform PCA on a subset"
错误: lexical error: invalid char in json text.
Driver: ENVI/ENVI .hdr Labelled
(right here) ------^
此外: 警告信息:
In CPL_gdalinfo(if (missing(source)) character(0) else source, options, :
GDAL Error 1: Zero positional arguments expected

I've tried to convert the sample data to ENVI format, but it still doesn't work

hi @liliy182 ,
the error is cause by the latest version of the package sf (1.0-19), which seems to produce an error when calling gdalUtilities::gdalinfo().

gdalUtilities::gdalinfo works correctly when using sf v 1.0-18

I suggest that you remove sf, and install the previous version using
remotes::install_version('sf', '1.0-18')

Thanks for the suggestion, I followed your method to install the sf package, but it is still the same error message, the problem does not seem to be solved,I'm wondering if it has something to do with my r version, my R version is 4.4.2 and Rtools version is 4.4

hi @liliy182 ,
did you restart R and make sure that sf v1.0-18 was correctly installed?

[liliy182]

Thanks for the reminder,I've restarted R and made sure I have installed sf v1.0-18 correctly,but it is still the same error message.

the bug should be fixed in v1.14.5
please update biodivMapR and let me know if the error persists
