Dose response curve

General
#1

Dear R Community,
I am doing an experiment for the fungicide sensitivity assay. I would like to prepare a dose-response curve.
kindly find the data format(concentration, Strain1, strain 2, strain 3) for your reference.
concentration in ug/ml and strain growth in Mm(millimeter)

|Con.|Strain 1|Strain 2|Strain 3|

|0.000|66.17|67.53|77.15|
|0.001|48.13|63.96|75.54|
|0.010|44.3|62.87|67.52|
|0.100|40.79|61.47|51.44|
|1.000|38.86|56.36|45.25|
|10.000|34.13|49.18|38.57|

I use R extensively but have no knowledge of medical/biological study.

Do you mean that you want to plot your data? Fit some kind of model? Or something else?

Please check the drc package: https://cran.r-project.org/web/packages/drc/drc.pdf

Yes would like to calculate EC50 and dose response curve
