Plot the density of one particular sample

1 2	plot_sample_density(obj, which_sample = obj$sample_to_covariates$sample[1], use_filtered = TRUE, units = "est_counts", trans = "log", offset = 1)

`obj`	a `sleuth` object
`which_sample`	a character string matching a sample in `obj$sample_to_covariates`
`use_filtered`	if TRUE, use filtered data. Otherwise use all data
`units`	either `'est_counts'` or `'tpm'`
`trans`	a string pointing to a function to use for the transformation.
`offset`	the offset so that transformations such as log don't compute -Inf. If NULL, then will not add an offset
