In my project I developed algorithms with R and R studio to process big images from microscopy analysis. I work on big matrix of pixel value (around 3Gb ), extract biological informations from specific regions of these images especially perform particle detection at specific position of the matrix and then perform statistical analysis.
To be able to transfer the whole process to other people without applying multiple scripts functions... I tried to create a Shiny App but I struggle to import the big images .txt
Actually I use as.matrix(read.table()) function on the file provided by the shiny app user through the file input box Is any one has an idea to import these matrix easily and more quickly ? even on Rstudio I wait ~20minutes for each picture import.
Thanks a lot in advance for the answers,
Best,
Romain
