这是使用base,我可以在其中控制x和y轴范围,其中应该精确绘制线条.

plot(mtcars$mpg, mtcars$hp, ylim = c(0, 400), xlim = c(0, 50), axes = F, xlab  = 'mpg', ylab = 'hp', pch = 16)
axis(side = 2, at = seq(100, 400, 100))
axis(side = 1, at = seq(10, 30, 10))

ggplot(data = mtcars, aes(x = mpg, y = hp))+geom_point()+
theme(panel.background = element_blank())+
scale_x_continuous(breaks = seq(10, 30, 10), limits = c(0, 50))+
scale_y_continuous(breaks = seq(100, 400, 100), limits = c(0, 400))

如何像基本曲线一样添加轴线？我已经尝试了scale_y_continuous,scale_x_continuous但它总是画到情节结束.

我有一维向量值。我想将它们转换为带有逗号分隔值的字符串。朱莉娅有一个简单的方法可以做到这一点吗？像崩溃一样r

{julia}

#I want output like this as a string

我正在尝试依赖于 MCR 的 matlab 脚本。我有包装脚本，可以在执行实际程序之前为此 MCR 目录设置环境变量。包装器如下。

#!/bin/csh

set thisdir = `pwd`

# --- SET UP ENVIRONMENT VARIABLES ---
echo --- setting up environment variables ---
# presumed location of MATLAB Component Runtime (MCR) v7.14
# if the MCR is in a different location, edit the line below
set mcr_root = /home/foo/MATLAB_Component_Runtime
echo $mcr_root
setenv LD_LIBRARY_PATH $mcr_root/v81/runtime/glnxa64:$LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH $mcr_root/v81/sys/os/glnxa64:$LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH $mcr_root/v81/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:$LD_LIBRARY_PATH

您有什么方法可以通过存储在字符中的查询来过滤data.table吗？对于.恩.

m <- structure(list(Hugo_Symbol = c("ABCA10", "ABCA4", "ABCC3", "ABCG4", 
"ACTBL2", "ADAMTS12", "ADCY5", "ADSS", "AGXT2", "ANG"), Variant_Classification = c("Splice_Site", 
"Missense_Mutation", "Missense_Mutation", "Missense_Mutation", 
"Missense_Mutation", "Missense_Mutation", "Missense_Mutation", 
"Splice_Site", "Missense_Mutation", "Missense_Mutation"), Variant_Type = c("SNP", 
"SNP", "SNP", "SNP", "SNP", "SNP", "SNP", "SNP", "SNP", "SNP"
), Tumor_Sample_Barcode = c("TCGA.AB.2988", "TCGA.AB.2869", "TCGA.AB.2887", 
"TCGA.AB.2934", "TCGA.AB.2931", "TCGA.AB.2945", "TCGA.AB.2833", 
"TCGA.AB.2912", "TCGA.AB.2822", "TCGA.AB.2988")), .Names = c("Hugo_Symbol", 
"Variant_Classification", "Variant_Type", "Tumor_Sample_Barcode"
), row.names = c(NA, -10L), class = c("data.table", "data.frame"
))

过滤

#These work fine
m[Variant_Classification %in% 'Splice_Site']
dplyr::filter(.data = m, filter = …

我正在尝试使用 ggplot2 绘制箱线图。样本数据是这样的。

> qplot(factor(genotype),count,data=sampe,geom="boxplot")

上面的命令产生这样的情节：

这里怎么了？？为什么会这样？？即使是下面的代码也会产生相同的输出。

ggplot(sampe,aes(x=factor(genotype),y=count))+geom_boxplot()
