formatting - Convert "(3e+04,3.5e+04]" type to number in r -


i have data set of car speed on road, , distance of car start point of measuring.

i wanted check mean , se in each 5 km down road, sorted data 'distancefromstart' , made table using function build:

speedbykm <- function(testfile){      setdt(a1a2011)[, list(speed=mean(speed)), by=list(cut(distancefromstart,breaks= seq(0, max(distancefromstart)+5000, = 5000),include.lowest=true))]->res     setdt(a1a2011)[, list(speed=se(speed)), by=list(cut(distancefromstart,breaks= seq(0, max(distancefromstart)+5000, = 5000),include.lowest=true))]->res1     res$se = res1$speed         return(res)  }

the table got is:

            cut    speed         se 1: (3e+04,3.5e+04] 88.16993 0.04784163  2:   (5e+03,1e+04] 94.33507 0.02121293  3: (2e+04,2.5e+04] 99.26032 0.03680951  4: (2.5e+04,3e+04] 90.31163 0.03991980  5:       [0,5e+03] 94.69139 0.01872111  6: (1e+04,1.5e+04] 94.70515 0.02661366  7: (1.5e+04,2e+04] 97.34650 0.02880336

how can make km show number? example, instead of '5e+03' show 5000? thank you.

increase dig.lab parameter default of 3:

x <- (1:5) * 1e3  cut(x, c(500, 2500, 5000)) #[1] (500,2.5e+03]   (500,2.5e+03]   (2.5e+03,5e+03] (2.5e+03,5e+03] (2.5e+03,5e+03] #levels: (500,2.5e+03] (2.5e+03,5e+03] cut(x, c(500, 2500, 5000), dig.lab = 4l) #[1] (500,2500]  (500,2500]  (2500,5000] (2500,5000] (2500,5000] #levels: (500,2500] (2500,5000]
