This article introduces the relevant knowledge of "what is the use of the R language parameter check.names". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

R language adds check.names=F parameters to read data such as read.table to ensure that special characters of the data can be read properly:

For example, the data header "-" is considered to be "."

> A=read.table ("F:/test/WGCNA/data/fpkm/All.DEG_final_3000.xls", sep= "\ t", check.names=T,header=T) > head (A 2) ID CK.WT.1 CK.WT.2 CK.WT.3 CK.tdr1.1 CK.tdr1.2 CK.tdr1.3 NaWT.1 NaWT.2 NaWT.31 AT1G01010 3.74149 7.3618 5.81734 5.71131 7.97054 10.37620 6.29949 5.55062 5.847792 AT1G01030 5.23528 2.66859 3.22632 1.32105 1.96726 2.40259 3.23077 4.80378 Natdr1.1 Natdr1.2 Natdr1.3 Na.WT. 1 Na.WT.2 Na.WT.3 Na.tdr1.1 Na.tdr1.2 Na.tdr1.31 15.58810 14.76360 17.74670 9.84943 7.97949 6.841060 13.29120 25.37000 19.599402 2.04301 2.29524 1.95286 1.83377 1.70757 0.809564 3.23172 1.80478 2.06044 SWT.1 SWT.2 SWT.3 Stdr1.1 Stdr1.2 Stdr1.31 4.96687 5.53349 3.18816 6.93650 7.88402 11 .250402 8.49256 2.65564 2.25570 4.35298 4.52147 7.11351 > A=read.table ("F:/test/WGCNA/data/fpkm/All.DEG_final_3000.xls" Sep= "\ t", check.names=F,header=T) > head (A 2) ID CK-WT-1 CK-WT-2 CK-WT-3 CK-tdr1-1 CK-tdr1-2 CK-tdr1-3 NaWT-1 NaWT-2 NaWT-31 AT1G01010 3.74149 7.3618 5.81734 5.71131 7.97054 10.37620 6.29949 5.55062 5.847792 AT1G01030 5.23528 2.66859 3.22632 1.32105 1.96726 2.40259 3.23077 4.80378 Natdr1-1 Natdr1-2 Natdr1-3 Na-WT- 1 Na-WT-2 Na-WT-3 Na-tdr1-1 Na-tdr1-2 Na-tdr1-31 14.76360 17.74670 9.84943 7.97949 6.841060 13.29120 25.37000 19.599402 2.04301 2.29524 1.95286 1.83377 1.70757 0.809564 3.23172 1.80478 2.06044 SWT-1 SWT-2 SWT-3 Stdr1-1 Stdr1-2 Stdr1-31 4.96687 5.53349 3.18816 6.93650 7.88402 11 . 250402 8.49256 2.65564 2.25570 4.35298 4.52147 7.11351

The data.frame () function also has character changes when combining data boxes, so you need to set check.names=F.
