发帖数: 142 | 3 一条直线上有大约 2 million 个点。
现在每个点和其他任何一个点都有一个interaction score，
在一定的score threshold 下现在已经有～ 10^12个这样的score。
data是这样的：
position1 position2 interaction_score
...
请问什么程序能handle这么大的data来plot interaction heatmap？
谢谢了。 |

发帖数: 142 | 5 When plotting histogram in R, how exactly R is using breaks? can someone
help me if I understand correctly?
e.g.
breaks=c(0,1,2,3)
default is right= TURE, means the following three bins:
(0,1],(1,2],(2,3]
or
???
so if the entries is 0, they will not be counted?
if I want to include the 0 class in the first bin, I use right= FALSE, but
then the 3 is not included?
is there some way I can set a bin as just one point, e.g. 0 ?
thanks! |

常见的是s3 method，比如说，你用plot函数，根据传递的参数不同，会相应出来不同

只需要一个generic function来定义很多method，但是s3缺点是，没法validate参数的

continuous probability distribution that is often used as a first

around a single mean value. The graph of the associated probability density
function is “bell”-shaped, and is known as the Gaussian function or bell
