Please run your sequence of R statements one at a time so you can tell where
the problem is. Only "run a script" after the code works one line at a time.
There are too many places where things can go wrong otherwise.
Is your file being read in properly? Is the filename correct? was the header
Thank you Rui. I ran the following script
df1 <- read.table("solar_hour", header = TRUE)
df1$date <- as.Date(paste(df1$year, df1$hour),
format = "%Y %j",
origin = "2012-08-01-0")
df2 <- df1[c("date", "IMF", "SWS", "SSN", "Dst", "f10")]
head(df1)
#To display all the rows
print(df2).
It gave me
library(lubridate)
library(dplyr)
df1 <- read.table(text = "YEAR DOY HR IMF SW SSNDst f10.7
