如何告诉摘要不包装列?

我正在尝试获取摘要以不包装其输出。但是,当我使用5列数据调用summary时,它会将第5列放在单独的行上。我希望有一种方法比手动打印迭代返回的对象更容易。

最诚挚的问候,

plotit.r

#!/usr/bin/Rscript
noneData <- read.csv("query.log", header=FALSE, sep="\t");
cnames = c( 'vids', 'partitions', 'localvert', 'remotevert',
                    'cachehits', 'responsetime' );
colnames(noneData) <- cnames;
cachenames = c('1', '2', '3', '4', '5');
responseCompare = data.frame(
   noneData$responsetime/1000000,
   noneData$responsetime/1000000,
   noneData$responsetime/1000000,
   noneData$responsetime/1000000,
   noneData$responsetime/1000000
   );
colnames(responseCompare) <- cachenames;
print("Response Times");
summary(responseCompare);

./ plotit.r #output:

options()函数为您提供了一种在R控制台环境中创建副作用的方法:

 names( options() )
 options(width=120) ; cat("Response Times"); summary(responseCompare)

然后,打印方法只有在达到“总页数”的120个字符时才会添加“\ n”。它计算列的宽度,一次只打印一批列。
