可能重复：
how to plot a bar chart with non-sorted x-axis (lattice)

我想绘制条形图。但我不知道如何用格子中未分类的x轴绘制它。默认情况下，晶格将对我不期望的x数据进行排序。

我的代码显示如下：

代码：

go=data.frame(number_of_Unigene=c(45,5328,30,30,119,3248,16594,244,4354,3547,917,429,3716,30,15726,4182,1673,877,30,30,640,4808,2462,2437,7812,190,2001,30,44,19852,1763,19852,31,30,686,30,3698,9829,3432,1439,15252,6024,1753,216,15917,15103,30,433,319,30,522,708,30,102,30,613,1039,30,2478),class=c("biological adhesion","biological regulation","carbon utilization","cell killing","cell proliferation","cellular component organization or biogenesis","cellular process","death","developmental process","establishment of localization","growth","immune system process","localization","locomotion","metabolic process","multicellular organismal process","multi-organism process","negative regulation of biological process","nitrogen utilization","pigmentation","positive regulation of biological process","regulation of biological process","reproduction","reproductive process","response to stimulus","rhythmic process","signaling","sulfur utilization","viral reproduction","cell","cell junction","cell part","extracellular matrix","extracellular matrix part","extracellular region","extracellular region part","macromolecular complex","membrane","membrane part","membrane-enclosed lumen","organelle","organelle part","symplast","antioxidant activity","binding","catalytic activity","channel regulator activity","electron carrier activity","enzyme regulator activity","metallochaperone activity","molecular transducer activity","nucleic acid binding transcription factor activity","nutrient reservoir activity","protein binding transcription factor activity","protein tag","receptor activity","structural molecule activity","translation regulator activity","transporter activity"),Ontology=c("biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","biological_process","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","cellular_component","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function","molecular_function"))

下

library(lattice)
barchart(go[,1]~go[,2],horiz=F,ylim=c(30,29666),layout=c(1,1),stack=F,
auto.key=list(space='right'),ylab="Number of unigenes",
scales=list(x=list(rot=45),y=list(log=T)))

我还应该做些什么？

Answer 1

一种方法是按照它们在数据中出现的方式重新排序因子b$class的级别：

newClass <- factor(go$class, levels = unique(go$class))

简介：

library(lattice)
barchart(go[,1]~newClass,horiz=F,ylim=c(30,29666),layout=c(1,1),stack=F,
         auto.key=list(space='right'),ylab="Number of unigenes",
         scales=list(x=list(rot=45),y=list(log=T)))

如何使用晶格绘制没有排序x轴的条形图？
