Issue82

[cvanderaa]

See #82 for background.

Here is an example after the new implementation where samples and carrier could be found in a set, but not in the other 2:

data(scp1)
scp1$SampleType[1:3] <- "foo" ## "foo" samples are only found in the first set
computeSCR(
    scp1, i = 1:3, colvar = "SampleType",
    samplePattern = "foo", carrierPattern = "foo"
)

(Expected) error:

Error in computeSCR(scp1, i = 1:3, colvar = "SampleType", samplePattern = "foo",  : 
  No match found with 'samplePattern = "foo"' for the following set(s):
190321S_LCA10_X_FP97AG, 190914S_LCB3_X_16plex_Set_21
No match found with 'carrierPattern = "foo"' for the following set(s):
190321S_LCA10_X_FP97AG, 190914S_LCB3_X_16plex_Set_21

Apologies for the formatting changes, you should only look into the code of computeSCR()...
