Hi,
I have a few hundreds files with numerical information of different length but with the same column structure. I use the following code to get summary statistics fplist <- list.files(pattern=".*analysis") for (fp in fplist){ x2 <- read.delim(fp) summary(x2) } Summary gives something like: summary (x2) V1 V2 V3 V4 V5 V6 V7 V8 V9 Min. :11.00 4:9 : 11 Min. : 1.00 Min. : 19128823 Min. : 19812573 Min. : 0.00 Min. : 1.00 Min. :0.1538 Min. : 1.000 1st Qu.:13.00 2:9 : 9 1st Qu.: 4.50 1st Qu.: 48952449 1st Qu.: 49085044 1st Qu.: 14.33 1st Qu.: 3.00 1st Qu.:0.7223 1st Qu.: 5.500 Median :20.00 3:10 : 9 Median :10.00 Median : 63129783 Median : 63218749 Median : 61.54 Median : 10.00 Median :1.0069 Median : 8.000 Mean :25.68 4:8 : 9 Mean :12.20 Mean : 72876334 Mean : 73051728 Mean : 175.39 Mean : 32.64 Mean :1.0522 Mean : 9.644 3rd Qu.:34.00 3:8 : 7 3rd Qu.:23.00 3rd Qu.: 96700016 3rd Qu.: 96713037 3rd Qu.: 264.88 3rd Qu.: 40.00 3rd Qu.:1.2586 3rd Qu.:12.000 Max. :72.00 4:13 : 6 Max. :23.00 Max. :203343850 Max. :204024777 Max. :1440.30 Max. :289.00 Max. :2.7690 Max. :27.000 (Other):300 V10 Min. : 6.00 1st Qu.:10.00 Median :14.00 Mean :18.03 3rd Qu.:24.00 Max. :52.00 Now I want to get a summary statistics of the summaries. Obviously I would need to store the summary results inarrays. But I was wondering if that makes sense and how an expert would solve this? I don't want to create an array for each column if possible.
