Microbes that decompose plant litter need water. Deserts with infrequent rains h

Microbes that decompose plant litter need water. Deserts with infrequent rains have very little of this water, so you would expect decay to happen slowly in these ecosystems. In general, you would be right. But researchers have found that rainfall is a bad predictor of how much decomposition happens in certain deserts. Instead, dew and fog play a key role in wetting plant litter.
Your task here is to figure out at what relative humidity is the leaf sensor more likely to be wet than dry. This assignment uses real data from Namib Desert, Namibia, to look at how likely the ground is wet given a certain relative humidity. The zip file for this project is here 03_merging_data.zip. Download 03_merging_data.zip and you should return this directory as a zip file with the provided data, the Rmd completed, a compiled html version of the Rmarkdown document, and the R-project files set.
You will need to:
1) read in the data and check that the numbers are reasonable
2) merge the data
3) find a cutoff for when the wetness percentage is ‘wet’
4) calculate the fraction of times the sensor was wet for a given relative humidity and figure out at what relative humidity is it more likely than not that the sensor is wet.
