As the war ends for me,
I have no regrets,
I’ve seen too much horror
I hope fate has been more merciful to you.
Our time on Earth is brief,
and mine has been filled with so much joy,
that i can only be thankful for
how much i’ve been blessed,
most specially for the wonder
you brought into my life.
This letter is my last,
I’ve been found guilty by a military court
for the death of an officer.
It was not my intention to kill him.
War makes men mad.
Though I failed Karl,
I know my sacrifice has not been in vain.
I fought for my country and my liberty,
my honour is assured.
Since it is the will of God to separate us on Earth,
I hope we’ll meet again in heaven.
Keep me in your prayers.
Your loving papa,
Always.
最近在看R shiny,挺有意思,等哪天得空自己拿过来玩玩,后来又想了一下,能否将其与statistical monitoring结合赋能,或者更进一步的使用网站进行NDA呢?
base R 用含 NA 的逻辑条件筛选数据框时,会保留 NA 位置,导致产生 NA 行。
df <- data.frame(
subjid2 = c("A", "B", "C"),
ok_fl = c("Y", NA, "N")
)
df[df$ok_fl == "Y", ]
>subjid2 ok_fl
>1 A Y
>NA <NA> <NA>
女朋友说她对我哪儿哪儿都不满意,呵呵,去找个让你哪儿哪儿都满意的男人吧!
老大昨天言辞恳切的对我说:“但行好事,莫问前程”。
在思考一个问题,未来10年内,使用R shiny进行NDA会不会成为最高效的递交方式?

换工作的那段时间将七月拜托给同事的母亲照顾,在一个农村的小院子里,结果没过两天因为应激跑丢了,我想他大概率已经回猫星了,对不起,我不是一个好主人。

发现一个有趣的事情,来自package xlsx的read.xlsx 和readxl的read_excel在读取xlsx文件时,前者会默认读取空白,而后者会将空白置换为NA;前者需要调用JAVA(如果电脑没有还需要安装),而后者不需要,速度要快的多。以后都用后面这个吧!
