yaxp problem for more irregular time series in one plot
...t more time series in one plot. As there are bigger
differences in values of variables I need logaritmic y axis.
The code I use is the following:
nvz_3_data <- read.csv('/home/tomas/R_outputs/nvz_3.csv')
date <- (nvz_3_data$date)
NO3 <- (nvz_3_data$NO3)
NH4 <- (nvz_3_data$NH4)
date_p <- as.POSIXct(date, "CET")
par(mfrow=c(2,1), ylog = TRUE, yaxp = c(0.01, 100, 3))
plot(date_p, NO3, log = "y", type = "l", col = "darkred", main = "NVZ-1",
xlab = "time", ylab = "NO3-" )
lines(date_p, NH4, col = "darkblue...

format (?) problems with data imported from postgres
...l <- dbGetResult(query_duj_kal)
My intention with the data is to create a time series by a following
script:
date <- (watchem_duj_kal$date)
NO3 <- (watchem_duj_kal$no3)
NH4 <- (watchem_duj_kal$nh4)
maxy<-max(NO3,NH4)
miny<-min(NO3[NO3>0],NH4[NH4>0])
date_p <- as.POSIXct(date, "CET")
par(mfrow=c(2,1), ylog = TRUE, yaxp = c(0.01, 100, 3))
plot(date_p, NO3,log = "y", type = "l", col = "darkred",
main = "NVZ-1", xlab = "time", ylab = "NO3-" )

1: states.trends(per.after.sub, "CUST_SINCE")
I use several tables:
1) full1, which contains data from 2009 to 2012
2) per2012.sub, which is a subset of full1 based on the criterion:
{ date_per = '2012-01-01'
date_per = as.POSIXct(date_per,tz='', "%Y-%m-%d")
per2012.sub = subset(full1, CUST_SINCE >= date_per) }
3) per.after.sub, which is a subset of full1 based on the criterion:
{ date_per1 = '2012-08-01'
date_per1 = as.P...
