perhaps we would like to look at only observations taken with a late time value. This allows us to ignore the early “noise” in the data and focus our analysis on mature birds. Returning to the subset function, we enter:

I found a dynamic programming solution which works when the combination is no more than one of each number. So Target 44 works but not my 307 example (returns Not Found). How can the multiples or number reuse be done? functionsubset(people, min, max) {varsubsets = []; subsets[0] =...
the primitive replacement operators such as “[<-” duplicate their first argument only if it is stored in two or more variables (or list elements), regardless of the context in which it is called. This violates the usual pass-by-value semantics of R function calls. For example, the call...
How to do DT[, lapply(.SD, uniqueN)] in base R, i.e. with data.frames ? –markus Commented Jan 22, 2019 at 12:50 3 .SD is a data.table function. It will not work on a data frame. The equivalent to work on a data frame would be sapply(DT, function(i)length(unique(...
Frist, human motif position frequency matrices were retrieved from JASPAR database using R packages JASPAR2020 v0.99 and BSgenome.Hsapiens.UCSC.hg38 v1.4.3, and getMatrixSet() function in R package TFBStools v1.31.2 (Tan and Lenhard, 2016). Then a hypergeometric test was performed to test ...

and they also play critical a role in antitumor immunity [78].Alternatively activated MØ(M2a MØ) have anti-inflammatory function and regulate wound healing [78]. M2a MØ can secrete large amounts of IL-10 in response to Fc receptor-γ (FcγR) ligation [80]. Interestingly, M2a MØ...
