可以用来简化代码，一般是在使用dplyr包或者是magrittr包时会出现，所以楼主需要安装和调用dplyr或magritt...
I am using RStudio to run this code, not sure if that makes any difference? Update: I have tried to examine the stat_cor function and found the following code: function (mapping = NULL, data = NULL, method = "pearson", cor.coef.name = c("R", "rho", "tau"), label.sep = ",...
In addition to the classic mutations generated by chemicals and ionizing radiations, transposable elements (P- elements) have played a key role in the relentless push to mutate every gene in the fly genome (Table 1). P-element-mediated gene discovery has introduced tran...
Structure does influence function. The team also discovered that no two chromosomes look the same, even in cells that are otherwise identical. To discover what each chromosome looks like in every cell in the human body will take far more work than one lab can take on alone. "It's not ...
"Another interesting aspect of our approach is that even as SARS-CoV-2 mutates, as long as the virus can still invade the cells we are mimicking, our nanosponge approach should still work. I'm not sure this can be said for some of the vaccines and therapeutics that are currently being ...
Unfortunately, many patients quickly develop a resistance to tamoxifen—sometimes as soon as a few months after they start taking it. This happens in a variety of ways—for example, sometimes the cancer cells will mutate to be able to kick the tamoxifen out of the cells, or simply produce ...
Unlike prior pandemics, we have a new and very powerful tool in 2020. We are able to obtain the RNA sequence of the virus almost in real time, and track the changes in the virus as it moves from place to place. These coronaviruses do mutate quite a bit. A group of dedicated scientis...
