I have data frame:
我有数据帧:
SINGLE_MEM crd
1 5 -97.75514500005232 30.263874000727306
2 8 -97.81095799930782 30.234157000528484)))
3 3 ((-97.68044500036247 30.267636999839592
4 2 -97.71808637589912 30.1848525102668))
5 10 -97.76847799967814 30.432537999903005
6 6 -97.6937453403672 30.46382579769979
In crd column i have coordinates in character. I need to replace all '( )' on a gaps. I replace ')', '))', ')))' by
在crd列中,我有字符的坐标。我需要替换空白上的所有'()'。我替换')',')')','),')by
df$crd <- gsub(")))", "", df$crd)
df$crd <- gsub("))", "", df$crd)
df$crd <- gsub(")", "", df$crd)
but i cant replace a '(', '((', '(((' because i have an error: Error in gsub ("((", "", df $ crd): Incorrect regular expression '((', reason 'Missing') ''
但是我不能替换一个'(',',','()(因为我有一个错误:gsub中的错误(",",",df $ crd):不正确的正则表达式'(',原因'Missing')”
