我已经将我的android库上传到https://bintray.com并将其与Jcenter存储库http://jcenter.bintray.com/相关联.现在我想从JCenter存储库中删除此库.我怎样才能做到这一点？
你建议的命令在某种程度上达到了目的但我仍然在寻找一个命令/函数来给出更平滑的曲线.我正在给出一个可重现的代码,它正在绘制相当尖锐的边缘或更粗糙:连接点的线太尖锐,特别是在它从一个点开始到另一个点的那一刻.很抱歉非技术语言,因为我仍然不熟悉该领域.感谢您提供有关此问题的帮助.请在下面的代码中建议修改以获得更平滑的曲线.
xdata1<-c(6:11)
ydata1<-c(-0.75132894, -1.71909555, -0.62653171, 0.49512191, 0.29201836, 0.31094460)
plot(NULL,NULL,xlim=xlims,ylim=ylims,axes=FALSE, ann=FALSE)
axis(1,cex.axis=0.7,mgp=c(3, .3, 0))
axis(2, las=1,cex.axis=0.7,at=c(-2,-1,0,1,2), mgp=c(3, .7, 0))
mtext(side = 1, text =expression('Year'), line = 1,font=15)
mtext(side = 2, text = expression('Variable'), line = 1.5,font=15)
lines(smooth.spline(xdata1,ydata1, df=5), col='red',type="l", pch=22, lty=1, lwd=1)
我必须绘制非常小的数据,时间步长为1.请参阅下面的示例数据:
xdata<-c(1:48)
ydata<- c(0.325563413,0.401913414,0.221939845,0.19881055,

请帮助我绘制平滑线,而不突出显示数据的各个点.
提前致谢,
我有一个像这样的矩阵
A=[ 1 2; 2 3; 3 4; 4 5; 5 6; 6 8; 7 9; 8 5; 9 4]
现在我想添加第二列,条件是如果limit = 0,interval = 3和limit = limit + interval,或者换句话说,我必须在第1列的值时对第2列求和,范围如0到3 ,3到6,6到9和9到12,我想要第2列的相应值的总和.
我的解决方案就是这样
range- sum
0 to 3 9
3 to 6 19
6 to 9 18
就像我有一个大约7000x2的矩阵.也可以给出序列号代替范围.
这只是一个例子.
我尝试以下代码
j <- "*Politics:* Disgraced peer Jeffrey Archer is set to make \xa31m from his Belmarsh "
nchar(j)
# Error in nchar(j) : invalid multibyte string 1
正如你所看到的,我无法使用nchar().我该如何解决这个问题？
当我尝试使用knitr编译PDF时,我收到以下错误:
there is no package called 'knitr' Error: object 'opts_knit' not found
Execution halted
我正在使用RStudio 0.97.332和R版本2.15.3.
可能是什么问题呢？
