Hello R
I have some data from a number of gels showing the distance of bands in
each gel and lane. My problem is to align these values by some method.

Hi All
I have looked but cannot find an answer to this.
I want to build a formula dynamically (in a function), using for example
paste, and using it in a model:

f1-formula(paste(fr, ~ SensoryTerm))

So this is the equivalent of

Using lapply and ending up with lists of lists I often end up in the

I am not sure exactly what you want to do but perhaps this is this
closer to what you need:

Hi
Are all your input p values the same? If so your output FDR values would
be the same.
Or are all your p-values relatively large? Then (nearly) all your FDR
values might be 1.
Why don't you put a small example up of what you did? Then we could see
what method you used etc.

[1] 2
[[3]]
[1] 3
How do you make it look like this with names? :
